Fixed Cage Compatible Mounts

Thorlabs' SM05, SM1, and SM2 lens tubes can be directly threaded into cage systems using our SM05, SM1, and SM2 cage plates, respectively. Additionally, metric threaded cage plates are offered for premounted aspheres and achromatic lenses as well as other small-diameter unmounted optics. Each mount has four through holes that accept our rigid ER rods. Using the rods and cage plates, structures can be built that share a common optical axis.
