Thorlabs' optical enclosures provide a protected space for instruments that are sensitive to light and acoustic vibrations. Our enclosures are made from our 25 mm rails and feature panels made of black hardboard, anodized aluminum, or plexiglass, which are held in place by the rail channels. Each is designed with an internal height of 12" (300 mm), and is available in lengths and widths ranging from 9" to 21" (225 mm to 525 mm). They ship partially assembled and can be fully assembled using a 1/8" (4 mm) balldriver or hex key (not included). Like any assembly based on 25 mm rails, our enclosures are completely customizable using the parts shown in the Construction Rail Accessories table to the right. For more information on how to build your own enclosure, please see the Custom Enclosures tab.

Breadboard Mountable
To install the breadboard of the correct size, flip the assembled enclosure upside-down and screw in four 1/4"-20 (M6) cap screws using the counterbored holes at each corner of the breadboard (see the image to the right). The corners of our stock enclosures are designed such that the 1/4"-20 (M6) tapped holes in the rail ends align with the counterbored holes in select sizes of our Aluminum Breadboards; please consult the Suggested Breadboards tables below to ensure the proper match. The enclosures can also be attached directly to an optical table using our breadboard mounting accessories. If you need an enclosure for a particular size of breadboard, we suggest contacting Tech Sales to discuss our custom enclosure options.

Integrated Door Options
Select enclosures are also available with a door assembly to provide easy access to the interior. We offer a black hardboard enclosure and plexiglass enclosure with a set of overlapping sliding doors that sit in a bottom-located slide track, which attaches directly to the breadboard. The tops of the sliding panels fit into the rail channel of the upper rail. Aluminum enclosures with hinged doors allowing access through two panels or top-only are also available. Plastic handles are included with both the sliding doors and the hinged door. Tracks for sliding doors are not available separately; please contact Tech Sales to include sliding doors in your custom enclosure.

Thorlabs' accessories for assemblies made of 25 mm rails include corner cubes and brackets, T-Nuts, low-profile channel screws, breadboard mounting accessoriesrail joiners, and a channel insert. In addition, we offer enclosure accessorieslaser safety fabric panels, and "do-it-yourself" tools like taps, tap guides, and drill guides for home-built XE25-based constructions.

XE25 Construction Techniques

Thorlabs' XE25 rails and components are the building blocks for many types of modular systems, including custom enclosures. For the most demanding applications, Thorlabs recommends the "direct connection" technique for forming right angles with rails, detailed here.


Step 1: Drill Side Holes

A Ø4.6 mm hole in the end of one rail, as shown in the picture to the right, is needed to provide access for a 1/8" (4 mm) balldriver.

For this step, you will need the T119873 Ø4.6 mm Drill Bit, the XE25DG Drill Guide, a hand drill or drill press, and a vise such as the TMV2.

The XE25DG drill guide is secured to the rail using the locking screw on top. A guide hole for the drill bit will be located 12.5 mm from the end of the rail. Now a hole can be drilled into the rail as shown in the figure to the left.

If your application requires a "three-way corner," such as that shown at the top of the page, you will have to drill a second hole in the rail at a 90° angle relative to the first hole.


Step 2: Tap the Center Hole, If Necessary

All stock and custom-length anodized XE25 rails have a 1/4"-20 (M6) tapped hole in the end of the rail. If you have cut a standard XE25 rail, or are using the XE25RL2 Raw Extrusion, you will need to tap a hole into the end of the rail.

For this step, you will need the 71598 1/4"-20 Tap (or the 71498 M6 Tap), the XE25TG Tap Guide, and the TW25 Hand Tap Wrench.

Fix the tap inside the tap wrench. Place the tap guide block over the end of the rail. The hole in the top of the guide will keep the tap square with the hole and minimize the chance of misthreading. Turn the tap to thread the hole.


Step 3: Attach Low-Profile Channel Screw

For this step, you will need a SH25LP38 1/4"-20-threaded (SH6M10LP M6-threaded) Low-Profile Channel Screw and a 1/8" (4 mm) balldriver.

Insert the screw into the threaded hole in the end of the rail, and tighten down partway with the balldriver. If you are making a three-way connection, you will need to thread another channel screw into the end of a second rail.


Step 4: Join the Rails

Slide the head of the channel screw into the channel of the rail with the drilled holes, so that the hex head lines up with the hole. Insert the balldriver into the hole, and tighten the channel screw. If making a three-way connection, repeat this process with the third rail, as shown in the figure to the right.

For increased stability, the corners may be reinforced with the XE25A90 Right-Angle Bracket.

This video provides step-by-step instructions on how to assemble a two-door, 1200 mm x 600 mm x
525 mm (L x W x H) enclosure with black hardboard panels. The parts needed for this custom enclosure are provided in the tables below.

Design a Custom Enclosure Using Thorlabs Components
With our vast selection of enclosure components, building your own DIY optical enclosure is simple. All our optical enclosure components, from panels to optical rails and corner cubes, can be purchased separately and customized to a size suitable for your application. For example, simple enclosures can be constructed to be as small as 1' x 1' x 1' (300 mm x 300 mm x 300 mm), whereas much larger enclosures are possible and might include hinged doors for easy access to an experiment. Enclosure components are designed to work together seamlessly, reducing the amount of time required during assembly.

Any side or dimension of the enclosure can be modified to suit the requirements of your application. The black hardboard enclosure panels can be cut to the appropriate size or drilled to accommodate integrating optomechanical components, like lens tubes. Alternatively, black-anodized aluminum panels are available with pre-drilled slots, for fiber and electrical panels, and an SM1-threaded (1.035"-40) through hole.

Should you choose not to build your own DIY enclosure, we welcome the opportunity to work with you to provide a custom enclosure that meets your specific requirements. Customizable options include enclosure dimensions, like panel sizes and optical rails; panel material, like black hardboard or black-anodized aluminum; and number and configuration of doors. We will ensure the proper fit and function of the customized components. Once the custom enclosure meets specification, we will ship the components for customer assembly. Please note that aluminum breadboards are not included with our custom enclosures and that enclosures will need to be assembled by the customer.

If you would like consultation regarding whether to place a custom order or which components you need to purchase in order to assemble your own DIY optical enclosure, please contact Tech Sales.

Custom Enclosure Example
This section details how to construct a two-door enclosure with black hardboard panels, which is shown completely assembled in the bottom-right image. Watch the video above for step-by-step instructions on how to assemble this particular enclosure. The size of this enclosure is 1200 mm x 600 mm x 525 mm (L x W x H). Refer to the tables below for a complete parts list. The enclosure was constructed from metric components, but it can also be constructed using the imperial equivalent components.

Custom enclosures can be built using our 25 mm rails and accessories. This two-door enclosure was constructed entirely from stock items. The video above provides step-by-step instructions on how to assemble this enclosure.
Custom Enclosure Back
Click to Enlarge
Two TB4 hardboards (cut to the required height) can be taped together using T743-2.0 Black Masking Tape to form the back panel of the enclosure.

This enclosure was assembled on a 600 mm x 1200 mm aluminum breadboard (24" x 48" for imperial components), though other breadboard sizes are possible. The left and right doors are 500 mm and 600 mm (20" and 24") wide, respectively. Each door can be opened separately, allowing access to the breadboard inside the enclosure. We recommend building the doors and frame of the enclosure separately and then assembling them to complete the enclosure. The rails used in the doors and frame are connected via construction cubes with slotted corners, which help to prevent light leakage at the corners of the enclosure, and are secured using low-profile channel screws. Alternatively, for a faster solution, our quick corner cubes can be used. Our TB4 hardboard, which constitute the panels of the enclosure, can be cut to size using a utility knife; these pieces fit directly into the slots of the 25 mm rails and the counterbores of the cubes. The back panel is formed using two pieces of hardboard cut to the desired length and height and taped together using T743-2.0 Black Masking Tape (see the image to the right). Note that, for the imperial enclosure, black masking tape will also be needed to connect the 24" x 24" panels together along the sides and back of the enclosure.

A 25 mm rail is installed along the top of the enclosure to mount the doors and door hinges. This rail is attached by drilling through the top two frame rails; see the video above for details. For details on drilling and tapping a hole into the top frame rails for precise placement of the support rail, see the Construction Methods tab above.

The height of the enclosure can easily be customized to fit any application. For best results when adding doors to your enclosure, the total door height with connection cubes should match the enclosure height minus the bottom rails; otherwise, the door will overlap with the bottom rail. We recommend using 500 mm (20") and 525 mm (21") long rails for the door and enclosure, respectively.

For applications requiring a light-tight enclosure, our BFP1 black flocked self-adhesive paper can be used to seal gaps in the hinges of the enclosure.

Thank you for contacting Thorlabs. For the XE25C11D/M enclosure, our suggested breadboard is MB4560/M. The suggested breadboards can be found by scrolling down the "Overview" section of our Optical Enclosures product family page.
Katherine Wood  (posted 2021-04-15 11:31:25.45)
Dear Thorlabs, Your optical enclosure stuff is great but one thing that would make everything a LOT easier is if you were to sell your black hardboards at 24.5" x 24.5" instead of 24"x24". Your standard longest rail is 24 inches, however you actually need a board 24.5" long to fit between a 24 inch rail since the board should fit inside the indentation of the rails. Thus, if you use the 24" rail, you have to cut up the boards and stick the bits back together with the black tape to make it long enough! Even 25x25" would be better since it would only then necessitate trimming off a bit rather than cutting up the boards. Thanks! Kath

Hello, The doors on the example with metric component can't be closed. Indeed there are 4 cubes whose dimensions are 25.4mmx25.4mmx25.4mm and 1 600mm rail and 1 300mm rail. If you assemble these elements, the total lenght is 1201,6mm which is greater than the 1200mm rail. To be sure to open and close the door, it's mandatory to reduce one of rail in order to insure sufficient gap between the rails.
llamb  (posted 2019-09-26 02:46:38.0)
Hello, thank you for your feedback. The metric-sized enclosure is confirmed to assemble and function properly with the metric parts list provided. The 1.6 mm difference in size that you have pointed out is not a concern when fully assembled. I have reached out to you directly to address any further concerns you may have.

How can I mount the XE25C11/M on the adviced breadboard? Do I have to acces the bottomside of the breadboard for this? How is this breadboard then mounted on an optical table?
YLohia  (posted 2019-07-09 09:28:21.0)
Hello, thank you for contacting Thorlabs. The vertical rails of the XE25C11/M would be mounted via the counterbored M6 holes located on the four corners of the breadboard. You may mount the breadboard to your table using a few CL5A clamps along the borders of the breadboard. Since there is not much room to work with along the borders of the breadboard, we recommend mounting the enclosure directly to the table using the XE25A90 right angle brackets.

The "example custom enclosure" cannot be assembled as shown using TB4 panels - being 24inx24in these panels will not engage the channels of the 4 uprights as shown … the panel width would have to be about 24.5in for the sides, and about 24.25in for each of the two panels used in the back.
llamb  (posted 2019-01-02 02:36:28.0)
Thank you for your feedback and for pointing this out. The original enclosure was physically built using the metric parts list, in which the construction rails are slightly shorter than those of the imperial parts list. You are correct that for the imperial dimensions, the enclosure would ideally have >24" hardboard panels to allow enough panel material to fit inside the construction rails' grooves. This can be rectified by using blackout tape to tape panels together, like what must be done for the 48" x 21" back section. We are updating this webpage to better point out the need for taping panels together in the imperial parts list, so thank you again for bringing this to our attention.

Response from Chris at Thorlabs: Thank you for using our feedback tool. This enclosure comes with two rails which are 52.5cm long. One of these is a standard rail having all four sides with the same extrusion profile, while the guide rail has one side which is different. Rather than having the standard opening which is only 0.26" across, it will have a larger 0.425" cutout to accommodate the doors. Please make sure this is the side you are trying to fit over the doors. If this does not solve your issue, please contact us at techsupport@thorlabs.com to further troubleshoot.

  • Rubber Anti-Vibration Dampeners Increase Stability
  • One AEPU1(/M) Enclosure Utility Panel Included

Our black-anodized aluminum enclosure is a sturdier alternative to plexiglass or hardboard enclosures when using higher-powered lasers (see the Damage Threshold Specifications table below). However, aluminum enclosures should not be used as permanent beam dumps; if your setup requires a beam dump, see our selection of beam traps and beam blocks.

The enclosure is designed with an internal height of 12" (300 mm). The L x W x H dimensions given in the product descriptions below are specified for the enclosure interior. The roof is shipped preassembled; a 1/8" (4 mm) balldriver or hex key (not included) is required to complete the construction. Rubber anti-vibration dampeners surround each enclosure panel to increase durability and stability, eliminating rattling when the enclosure is moved.

The enclosure includes one AEPU1(/M) enclosure utility panel that features four RBX-BLK1F blank connection panels and one SM1-threaded (1.035"-40) through hole covered by a removable SM1CP2M end cap. The blank connection panels can be removed for easy installation of our fiber or electrical connection panels (see the image to the left). The SM1-threaded hole allows for a range of SM1-compatible components, like our lens tubes, to be installed.

The corners of the enclosure are positioned such that the 1/4"-20 (M6) tapped holes in the rail ends align with the counterbores in our Aluminum Breadboards (sold separately). Please consult the Suggested Breadboards table above and to the right to ensure the proper match.

We also offer a version of this aluminum enclosure with a hinged door, item # XE25C11D(/M), below.

  • Black Hardboard or Plexiglass Panels
  • 21" x 15" x 12" (525 mm x 375 mm x 300 mm)
  • Sliding Side Panels with Rigid Plastic Handles

Our enclosures with door assemblies feature black hardboard or plexiglass panels and a sliding door assembly on one side. This assembly consists of two overlapping doors with plastic handles that slide along the channel of the rail above and the track bolted to the breadboard underneath. Please note the doors in the XE25C9D(/M) enclosure include a widened channel, indicated by engraved dots, to allow for each panel to slide over the other; see the image to the far right.

These enclosures come complete with all the enclosure components necessary for construction (please note that the breadboard is not included). The roof is shipped preassembled, but note that a 1/8" (4 mm) balldriver or hex key (not included) is required to complete construction of the enclosure, and a 9/64" balldriver or hex key (not included) will be needed to attach the handles to the doors.

The corners of our stock enclosures are positioned such that the 1/4"-20 (M6) tapped holes in the rail ends align with the counterbores in our aluminum breadboards (sold separately). Please consult the Suggested Breadboards table to the right to ensure the proper match.

The side panels on these enclosures can be replaced with our aluminum enclosure panels. The black hardboard sliding door kit is also available separately [item # XE25DK1(/M)].

  • Anodized Aluminum Enclosure with Hinged Door
  • 21" x 15" x 12" (525 mm x 375 mm x 300 mm)
  • Rubber Anti-Vibration Dampeners Increase Stability
  • One AEPU1(/M) Enclosure Utility Panel Included

This black-anodized aluminum enclosure includes a hinged edge that allows the top and front panels to swing open, granting access to the interior. As with the XE25C11(/M) enclosure sold above, the aluminum construction provides a sturdier alternative to plexiglass or hardboard enclosures when using higher-powered lasers (see the Damage Threshold Specifications table below). Aluminum enclosures should not be used as permanent beam dumps; if your setup requires a beam dump, see our selection of beam traps and beam blocks.

The enclosure is designed with an internal volume of 21" x 15" x 12" (525 mm x 375 mm x 300 mm). The hinged top panel is shipped preassembled with the exception of the support brackets; a 1/8" (4 mm) balldriver or hex key (not included) is required to attach these brackets as well as the four side panels. Support brackets (included) should be added to the corners of the top and back panels, as shown in the image to the upper right, in order to stabilize the enclosure in the fully open position. Rubber anti-vibration dampeners (included) should be added to the edges of each enclosure panel to increase durability and stability and to eliminate rattling when the enclosure is moved.

We recommend installing two XE25LS lid stops (sold separately) on the back rail of the top panel in order to hold the enclosure door fully open. The lid stops can be installed using our T-nuts and low-profile screws in the rail channel. The image to the upper right shows an XE25LS lid stop near one end of the rail. For setups where a fully open door is not desired, we recommend the XE25GSK door opener kit (sold separately), which holds the door open at 90°, as seen in the image to the left. If space is at a premium, we recommend the XE25LB bracket (sold separately) to hold the lid of the enclosure open.

The enclosure includes one AEPU1(/M) utility panel that features four RBX-BLK1F blank connection panels and one SM1-threaded (1.035"-40) through hole covered by a removable SM1CP2M end cap. The blank connection panels can be removed for easy installation of our fiber or electrical connection panels. The SM1-threaded hole allows for a range of SM1-compatible components, like our Ø1" lens tubes, to be installed.

The corners of the enclosure are positioned such that the 1/4"-20 (M6) tapped holes in the rail ends align with the counterbores in our Aluminum Breadboards (sold separately). Please consult the Suggested Breadboards table above and to the right to ensure the proper match.
