Thorlabs offers several styles of cage plates for our popular 60 mm Cage System. Standard plates are designed to hold Ø2" optics with various thicknesses. SM2-threaded versions are designed to interface with our Ø2" Lens Tubes and SM2-threaded optics. For applications requiring quick changes in components, we offer both quick release cage plates and removable cage segment plates. To connect cage systems to a Cerna microscope or certain Nikon microscopes, we provide cage plates with dovetails.
