Self-Centering Lens Mount for 60 mm Cage Systems
60 mm Cage-Compatible
SCL60C Holding an ACL4532 Ø45 mm
The three spring-loaded fingers of Thorlabs' 60 mm Cage-Compatible Self-Centering Lens Mount firmly grip optics ranging from Ø0.15" (Ø3.8 mm) to Ø1.77" (Ø45.0 mm) that are no heavier than 1.0 lb. The fingers are easily opened with one hand by pinching the actuator tabs between the thumb and forefinger. The lens is held bewteen the mounting fingers as the actuator tabs are released. The nested ring design centers the optic within a 60 mm Cage System. The mount features four through-holes to accommodate our ER Series Cage Rods and eight 4-40 setscrews to lock them into place. A bottom-located 8-32 (M4) tapped hole also allows for direct fastening to our Ø1/2" Posts.
For post-mounting applications outside of a cage system, or if larger diameter optics up to Ø3.00" (Ø76 mm) need to be accommodated, Thorlabs offers Self-Centering Lens Mounts.
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.
