SM05 Compatible Cage Plates


SM05 Compatible Cage Plates

  • 0.535"-40 Threading
  • Mount SM05 Lens Tubes in a 16mm Cage Structure


  • Integrate SM05 Series Lens Tubes with 16 mm Cage Systems
  • SM05 (0.535"-40) Internally Threaded Through Holes
  • Compatible with SR Series Cage Construction Rods

Thorlabs introducted the SM Series Threading standards to ensure compatibility over a broad range of product lines. SM Series Threaded components offer a simple and efficient solution for building optomechanical structures. The SM Threaded products available, including lens tubes and cage system components, fixed and kinematic mounts, irises and diaphragms, provide flexibility when constructing complex optical systems.

SM05 Threaded (0.535"-40) cage plates and cage cubes allow SM05 Lens Tubes to be integrated into 16 mm Cage Systems.


16 mm Cage Cube and Accessories

* Four Sides with SM05 (0.535"-40) Threads
* 2 Opposing Sides with Ø0.635" Through-Holes
* #4-40 Tapped Holes on Each Side
* Mounts to SR Series Cage Rods

Cage cubes are key components of our optomechanical cage assemblies. They are an ideal way to join multiple subsystems via a centrally located interface. These components can also act as an instrumentation box for small electro-optical components. The solid one-piece construction, machined parallel and perpendicular to within 0.002" (0.05 mm), maintains excellent alignment of joined subsystems.

Prism Mount
The SPM2 prism mount can be used to mount a prism or cube optic up to 10 mm tall for integration into a compact cage system. This mount can be used with the 16 mm cage cube SC6W, or any cage mount with a Ø0.635" aperture. Full 360° rotation can be accomplished by rotating the complete mount when attaching it to the cube to make adjustments, prior to securing it into place using a #4-40 nylon-tipped setscrew. Epoxy is required to secure an optic onto the mount.

Cage Cube Clamp
The SB6C cage cube clamp is compatible with the SC6W 16 mm cage cubes. The clamping mechanism is a #10-32 adjuster with a 3/32" hex socket head and a Delrin swivel tip to help avoid marring the clamped object. A 3/32" hex key is included with each SB6C. Depending on the optical component being mounted, either a blank cage plate (SP01) or a prism mount (SPM2) can be used as the base for this clamp. When using an SP01 with this clamp, rectangular prisms between 0.4" (10.2 mm) and 0.75" (19 mm) tall.


SM05 Threaded Cage Plate


  • Four Through-Holes that Accept SR-Series Rods
  • 0.535"-40 Thread with Retaining Ring for Securing an Optic or SM05 Lens Tube
  • 4-40 or M3 Tapped Holes Allow Mounting to Mini Series Posts
  • Connects to SC6W Using the Provided 3-48 Cap Screws

This SM05-Threaded Cage Plate is designed for use with our compact 16 mm cage assembly system. It features four through-holes that accept Ø4 mm SR Series cage rods. Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key. In addition, 3-48 cap screws are included for bolting it onto the SC6W six-way cage cube. One SM05RR retaining ring is included.


SM05 Quick-Release Cage Mount for the 16 mm Cage System

* Compatible with 16 mm Cage Systems
* Unique Dovetail Design Provides Smooth Release and Clamping Action
* One-Handed Operation for Removal and Repositioning of an Optic
* Accepts Ø1/2" (12.7 mm) Optics Up to 0.12" (3 mm) Thick
* SM05 Internal Thread Directly Compatible With Our SM05-Series Components

The QRC05A cage mount is equipped with a unique spring-loaded dovetail design used to engage cage rods for positioning. By simply squeezing the dovetails together via the cupped actuator levers, the dovetail mechanism disengages the cage rods, allowing the mount to be either quickly repositioned or completely removed from a cage assembly. This convenient one-handed mechanism does not require any additional tools to actuate the clamping mechanism.


Our Mission is to accelerate the advancement of optical technology for precision measurements and their applications from the table tops of research laboratories to standard use in communication and high technology industries. Our aim is to serve our customers. Our hope is to create a place for highly skilled people in an open environment
