Features

  • 30 mm and 60 mm Cage System Fixed Mounts Available
  • Mount Ø1/2", Ø1", Ø2", or 2" x 2" Optics
  • Quick Installation and Removal of Optics
  • Post Mountable via 8-32 (M4) Tapped Holes

The mounts offered below are for installing a single filter in-line within a cage system. See the Filter Mount Selection Guide to the right for other mounting options.

The CFH1R and LCFH1(/M) Removable Filter Holders are based upon a precision spring-loaded dovetail design, ensuring good position stability and repeatability. These filter holders are designed to hold Ø1/2" or Ø1" optics, respectively, using the included retaining ring. Additional plates are available to easily mount and then switch optical components.

The CFH2R(/M) and LCFH2(/M) Removable Filter Holders are light-tight, stackable filter blocks designed to integrate easily into our 30 mm or 60 mm cage systems or to be post mounted on a breadboard. Unlike the CFH1R and LCFH1(/M), this light-tight design is achieved with a permanent O-ring mounted on the front face and a double-flanged top plate on the removable inner body.

The LCP05A(/M) 60 mm Cage Plate for Square Filters, has a Ø2" (50.8 mm) through hole (Ø1.65" (Ø41.9 mm) clear aperture) and is designed to hold either 2" (50.8 mm) or 50 mm square filters up to 0.16" (4.0 mm) thick. Since the mount is equipped with two spring clips on each side, a filter can be pressed up against either side of the clear aperture. This filter holder is ideal for use with our 2" x 2" Unmounted Absorptive Neutral Density Filters or our Square Colored Glass Filters.

Response from Javier at Thorlabs to yogeshrwagh: Thank you for your feedback. We do not have a filter holder for 1" optics with similar design as that of the CFH1. However, I would recommend using the CP09F 30 mm cage plate assembly with a magnetic, removable front plate. We offer the front plate separately so that you can mount different filters and still use the same back plate, which is supported by ER rods.

Ø1" Removable Filter Holder

  • Mounts Ø1" Optics up to 0.29" (7.4 mm) Thick
  • Compatible with 60 mm Cage Systems
  • SM1-Threaded on One Side of the Insert
  • Post Mountable via 8-32 (M4) Tap

The LCFH1(/M) Removable Filter Holder is a stackable filter block designed to integrate easily into our 60 mm cage system or to be post-mounted on a breadboard. The filter holder offers internal SM1 (1.035"-40) threading with a fixed retaining lip and an SM1RR retaining ring. It can hold Ø1" optics up to 0.29" (7.4 mm) thick.

The precision, spring-loaded, dovetail design of the removable inner body ensures reproducible positioning and eliminates unwanted movements to ensure repeatability. Multiple filter holders can be continually stacked in our 60 mm cage system, provided an equivalent length of cage rods is available for support. All four of the cage rods can pass through the cage rod clearance holes on the LCFH1(/M).

Extra SM1-threaded filter plate inserts (Item # LCFH1-F) are available separately. In addition, the LCFH1-B Blank Plate Insert can also be purchased separately. The blank plate can be used as a manual shutter or can be machined to suit your specific requirements, with the aid of the center drill mark.

CFH2R Schematic
  • Mounts Ø1" Optics up to 0.31" (8.0 mm) Thick
  • Compatible with 30 mm Cage Systems
  • SM1-Threaded on Both Sides
  • Light-Tight Design
  • Post Mountable via 8-32 (M4) Tap
  • Extra Filter Holder, Blank Plate, or Variable Attenuator Insert Available Separately
    • Inserts are Compatible with CFH2R(/M) and Previous-Generation CFH2(/M) Filter Holders

The CFH2R(/M) Removable Filter Holder is a light-tight, stackable filter block designed to integrate easily into our 30 mm cage system or to be post mounted on a breadboard. Unlike the CFH1R above, this light-tight design is achieved with a permanent O-ring mounted on the front face and a double-flanged top plate on the removable inner body.

Filter Holder
The filter holder can accommodate Ø1" optics up to 0.31" (8.0 mm) thick and is equipped with SM1-threaded (1.035"-40) faces, making it compatible with any of Thorlabs' SM1-threaded components. The precision, spring-loaded, dovetail design of the removable inner body ensures reproducible positioning and eliminates unwanted movements to ensure repeatability.

The top plate features two laser-engraved boxes for labeling and identification of the mounted optic. Multiple filter holders can be continually stacked in our 30 mm cage system provided an equivalent length of cage rods is available for support. The cage rods can pass through the cage rod clearance holes on the bottom of the CFH2R(/M); however, they thread into the top. Extra SM1-threaded filter plates (CFH2-F) are available separately.

Blank Plate
In addition, the CFH2-B Blank Plate, also purchased separately, can be used as a manual shutter or machined to suit your specific requirements. It features two top-located, laser-engraved boxes for labeling.

Variable Attenuator Insert
The CFH2-V is a variable attenuator insert for the CFH2R(/M) and previous-generation CFH2(/M) holders equipped with a black-oxide-coated variable single-blade shutter to partially or fully block light. The shutter moves vertically from the top across the Ø0.54" aperture and is intended for a maximum 0.50" beam diameter. Shutter position is controlled with a 3/16"-120 adjuster that provides 0.005" shutter translation per revolution; fine adjustments can be performed with the included 5/64" hex key. To quickly close the shutter, press the adjuster down (see photo above); letting go of the adjuster will return the shutter to the set position (within 0.0005"). For best performance, light after the attenuator insert should be coupled into a fiber optic patch cable as the output beam profile will not be circular.

Ø2" Removable Light-Tight Filter Holder

  • Mounts Ø2" Optics up to 0.30" (7.6 mm) Thick
  • Compatible with 60 mm Cage Systems
  • Housing is SM2-Threaded on Both Sides
  • Light-Tight Design
  • Post Mountable via 8-32 (M4) Tap

The LCFH2(/M) Removable Filter Holder is a light-tight, stackable filter block designed to integrate easily into our 60 mm cage system or to be post mounted on a breadboard. Unlike the LCFH1(/M) above, this light-tight design is achieved with a permanent O-ring mounted on the front face and a double-flanged top plate on the removable inner body.

The filter holder insert can accommodate Ø2" optics up to 0.30" (7.6 mm) thick and is equipped with SM2 (2.035"-40) threading on one side and a fixed retaining lip on the other. The optic is held in place with the included SM2RR retaining ring. The housing of the filter holder has SM2 threading on both sides for easy integration into an SM2 lens tube system. The precision, spring-loaded, dovetail design of the removable inner body eliminates unwanted movements to ensure reproducible positioning. The spring-plunger tension of the LCFH2(/M) can be adjusted via the slotted setscrew located on the side of the housing if necessary.

Multiple filter holders can be continually stacked in our 60 mm cage system, provided an equivalent length of cage rods is available for support. The cage rods can pass through the cage rod clearance holes on the bottom of the LCFH2(/M); however, they thread into the top holes.

Extra SM2-threaded filter holder inserts (LCFH2-F) are available separately. In addition, the LCFH2-B Blank Plate, also sold separately, can be used as a manual shutter or machined to suit your specific requirements. All of these items feature two laser-engraved boxes for labeling on the top.
