HeNe to 60 mm Cage System Adapter Plate
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.
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.
