Ø5.6 mm and Ø9 mm TO Can Kits
Each LDH56-P2(/M) or LDH9-P2(/M) Collimation Mount Kit includes cage plates for mounting either a Ø5.6 mm or Ø9 mm laser diode (CP1LM56 or CP1LM9, respectively), an M9-threaded cage plate (CP1TM09) for holding a mounted aspheric lens, and four 1.5" long cage rods. Precision mounting of the lens and laser diode without the use of adapters ensures maximum centration for good beam quality and alignment to the cage system. The distance between the laser diode and lens can be precisely set using a 3/16"-100 adjuster (5/64" hex). The mount is compatible with our SR9 strain relief cables.

TO-3 Can Kit
The LDH3-P1 Collimation Mount Kit holds a TO-3 laser diode and an M9 x 0.5-threaded aspheric lens. It uses an S1TM09 adapter and CP02 cage plate to mount the aspheric lens and does not incorporate a hex adjuster. This kit includes four 1.5" long cage rods.

Laser Diode Temperature Warning
Please note that these laser diode cage plate mounts do not have any temperature regulation or temperature measurement capability, so we do not recommend using them with higher power laser diodes. Running a laser diode at a high operating temperature can significantly shorten its lifetime.

Cage System Overview

The Cage Assembly System provides a convenient way to construct large optomechanical systems with an established line of precision-machined building blocks designed for high flexibility and accurate alignment.

16 mm, 30 mm, and 60 mm Cage System Standards

Thorlabs offers three standards defined by the center-to-center spacing of the cage assembly rods (see image below). The 16 mm cage, 30 mm cage, and 60 mm cage standards are designed to accomodate Ø1/2", Ø1", and Ø2" optics, respectively. Specialized cage plates that allow smaller optics to be directly inserted into our larger cage systems are also available.

Standard Threads

The flexibility of our Cage Assembly System stems from well-defined mounting and thread standards designed to directly interface with a wide range of specialized products. The three most prevalent thread standards are our SM05 Series (0.535"-40 thread), SM1 Series (1.035"-40 thread), and SM2 Series (2.035"-40 thread), all of which were defined to house the industry's most common optic sizes. Essential building blocks, such as our popular lens tubes, directly interface to these standards.

Cage Components
Cage Rods 16 mm These rods are used to connect cage plates, optic mounts, and other components in the cage system. The SR Series Cage Rods are compatible with our 16 mm cage systems, while the 30 mm and 60 mm cage systems use ER Series Cage Rods.

Cage Plates 16 mm These serve as the basic building blocks for a cage system. They may have SM-threaded central bores, smooth bores sized for industry standard optics or to accommodate the outer profile of our SM Series Lens Tubes, or specialized bores for other components such as our FiberPorts.

Post and Breadboard Mounts and Adapters Mounting options for cage systems can be found on our Cage System Construction pages. Cage Systems can be mounted either parallel or perpendicular to the table surface.
Size Adapters Cage System Size Adapters can be used to integrate components from different cage system and threading standards.
Specialized Components Thorlabs also produces specialized cage components, such as Filter Wheels, a HeNe Laser Mount, and a FiberPort Cage Plate Adapter, allowing a wide range of our products to be integrated into cage-mounted optical systems.

How much current/heat can be allowed for these products?
jlow  (posted 2014-07-29 03:57:57.0)
Response from Jeremy at Thorlabs: There's no temperature regulation for these mounts so it should be used for low-power LD only. The max. current would depend on the individual laser diode you are using.

  • Components available separately below (Click here to purchase ER1.5).

Laser diodes are secured into the CP1LM56 or CP1LM9 cage plate mounts by tightening a retaining ring (left). Access holes (right) allow the laser diode to be rotated using tweezers and the notches in the laser's housing.

  • Complete Mounting Hardware (Laser Diode, Strain Relief Cable, and Aspheric Lens Not Included)
  • Kits for Mounting Ø5.6 mm or Ø9 mm Laser Diodes Available
  • M9 x 0.5-Threaded Cage Plate for Mounting Aspheric Lenses
  • 0.75" (19.1 mm) Long 100 TPI Fine Hex Adjuster for Lens Positioning
  • Kits Ship Preassembled

The LDH56-P2(/M) and LDH9-P2(/M) Collimation Mount Kits are 30 mm cage system assemblies that hold a user-provided Ø5.6 mm or Ø9 mm TO can laser diode and a user-provided M9 x 0.5-threaded aspheric lens. Each kit includes a cage plate for mounting either a Ø5.6 mm or Ø9 mm laser diode (CP1LM56 and CP1LM9 respectively), as well as an M9-threaded cage plate (CP1TM09) for holding the aspheric lens. Precision mounting of the lens and laser diode without the use of adapters ensures maximum centration for good beam quality and alignment to the cage system. The distance between the laser diode and lens can be precisely set using a 3/16"-100 adjuster (5/64" hex, Item # F19SS075).

The laser diode is secured with a retaining ring that can be tightened using a spanner wrench. The Ø5.6 mm mount is compatible with our SPW801 spanner wrench only, while the Ø9 mm kit is compatible with the SPW301 and SPW801 spanner wrenches. To align the laser chip axis to the cage system, access ports on the front of the mount allow rotation of the laser diode using tweezers prior to fully threading the retaining ring (see photo to the right). After the laser diode is mounted, a strain relief cable can be screwed into the back of the cage plate for electrical connections.

This collimation mount can be integrated into a 30 mm cage system by threading the ER1.5 cage rods onto a longer cage section or by mounting the two cage plates directly onto a longer cage section. Individual components are also available below, including cage plates that hold unmounted optics or aspheric lenses with housings based on other thread standards. The laser diode mount cage plates are also available separately below.

  • The metric version of the CP04 is not available separately from Thorlabs, while the imperial version is available below.
  • This previous generation item is not available for purchase separately. The CP33(/M) cage plate can be used if a replacement for the CP02(/M) cage plate is required..

  • Compatible with Standard Heat Sinks for TO-3 Laser Diodes
  • Kit Ships Preassembled

The LDH3-P1(/M) Collimation Mount holds a TO-3 laser diode and a M9 x 0.5-threaded aspheric lens. It uses an S1TM09 adapter and CP02 cage plate to mount the aspheric lens. Unlike the LDH56-P2 and LDH9-P2 collimation mounts described above, this mount does not feature a hex adjuster and only offers coarse positional adjustment of the laser diode and lens cage plates. Fine adjustment of an aspheric collimating lens relative to the laser diode package can be accomplished by rotating the S1TM09 lens adapter. The LDH3-P1 can be mounted directly onto any heat sink that is designed to accept TO-3 laser packages.

This collimation mount can be integrated into a 30 mm cage system by threading the ER1.5 cage rods onto a longer cage section or by mounting the two cage plates directly onto a longer cage section. Individual components are also available below, including cage plates that hold unmounted optics or aspheric lenses with housings based on other thread standards. The laser diode mount cage plates are also available separately below.

Individual 30 mm Cage Plates for Unmounted Optics from Ø5 mm to Ø20 mm

  • Mount Ø5 mm to Ø20 mm Optics
  • Ideal for Use with Unmounted Aspheric and Achromatic Lenses
  • Two Retaining Rings Included for Mounting Optic
  • Compatible with 30 mm Cage Systems
  • Not Post Mountable
  • These Cage Plates Can be Used in Place of the CP1TMxx Cage Plates when Constructing the Kits Sold Above

These cage plates are designed for mounting optics that have a diameter up to 20 mm, such as our unmounted aspheric and achromatic lenses, into a 30 mm cage system. They have M5.5, M6.5, M8.5, M9.5, M15.5, 0.750"-40, or M20.5 internal threads and include two retaining rings of the appropriate size to secure the optic. The SPW801 spanner wrench is recommended when threading the retaining rings into place.
