Features

The HCM2 Adapter Plate is designed to enable integration of a cylindrical HeNe laser with a diameter between 1.74" and 1.77" (44.2 mm and 45.0 mm) into a 60 mm cage system or SM2 (2.035"-40) lens tube system. This adapter allows ±1.0 mm (0.04") of coarse X & Y manual translation for positioning of the laser source. The slip-plate design provides smooth, easy adjustments and and the position can be locked using four 5/32" (4 mm) hex screws. A pair of double-bored mounting plates ensures a true 3-point contact for stable mounting of the HeNe laser using two nylon-tipped 5/64" (2 mm) hex setscrews. Two 8-32 (M4) taps allow the HCM2 to be mounted on our standard Ø1/2" posts or Ø1" posts with 8-32 (M4) taps.

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 System 16 mm 30 mm 60 mm
Thread Series SM05 SM1 SM2
Rod to Rod Spacing 16 mm (0.63") 30 mm (1.18") 60 mm (2.36")

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.
30 mm
60 mm
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.
30 mm
60 mm
Optic Mounts 16 mm Thorlabs offers fixed, kinematic, rotation, and translation mounts specifically designed for our Cage Systems.
30 mm
60 mm
Cage Cubes 16 mm These cubes are useful for housing larger optical components, such as prisms or mirrors, or optics that need to sit at an angle to the beam path, such as beamsplitters. Our cage cubes are available empty or with pre-mounted optics.
30 mm
60 mm
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.

Is this compatible with the 60mm mounting base (LCPB1) so it can be bolted down to an optical table/breadboard without the use of posts?

Thank you for your feedback. Yes, the HCM2 can indeed fit onto the LCPB1. They can be connected using a #8-32 cap screw, or an M4 cap screw in the case of the HCM2/M and the LCPB1/M.

One comment: the metric version (HCM2/M) has a 101.6mm (4 inch) separation between the four M4 mounting holes, which means that it can't be mounted to a metric breadboard without extra elements (e.g. base plates). It would probably make sense to design this part with a 100mm separation in a future revision.

Thank you for your feedback. We have reviewed the design and we will be shifting the mounting holes so they will be 100mm in the future for the HCM2/M.

Response from Buki at Thorlabs: The HCM2 XY adjustable HeNe mount is designed for 1.75" diameter HeNe lasers. Our 5mW HeNe lasers has a 1.74" diameter, so they will fit. Below is a link to our selection of HeNe lasers, including the 5mW version. http://www.thorlabs.us/NewGroupPage9.cfm?ObjectGroup_ID=1516 This mount is not designed for thermal stability. Please contact TechSupport@thorlabs.com if you hae additional questions or wish to discuss your application.

Is there a limit to how big the HeNe is? Would some or all of the 5 mW or greater HeNes fit? Is this thermally stable?
