30 mm Cage Plates

Thorlabs offers several styles of cage plates for our popular 30 mm Cage System. Standard plates are designed to hold Ø1" optics with various thicknesses. SM1-threaded versions are designed to interface with our Ø1" Lens Tubes and SM1-threaded optics. For applications requiring quick changes in components, we offer drop-in cage mounts, 30 mm cage to dovetail adapters, a cage plate to post adapter, and removable cage segment plates. Translating or rotating cage segment plates allow for rotational or lateral offsets, respectively, between cage system segments. A 30 mm cage system-compatible U-Bench mount is offered to provide setups a 2.50" gap. Additionally, a variety of cage plate adapters are available to integrate 30 mm cage systems with our Ø1/2" posts, FiberBenches, and 66 mm rails.
