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 both quick release cage plates and removable cage segment plates. A 30 mm cage system-compatible U-Bench mount is offered to provide setups a 2.50" gap.
