thingiverse

Two adapters for goniometer tilt adjustment device [GN1/M](https://www.thorlabs.de/thorproduct.cfm?partnumber=GN1/M) from Thorlabs: one ring adapter and one cage adapter. The ring adapter is designed to mount 2-inch diameter lenses on the goniometer, positioning its optical axis 1 inch above the top surface of the device, aligning it with its rotation axis. The adapter can be secured to the goniometer's top plate using two M3 screws or simply glued into place. An M3 screw is used to fasten the lens within the adapter, and the top hole of the ring must be tapped for this purpose. The cage adapter allows the goniometer to be inserted into a 60-mm optical cage system. The rotation axis of the goniometer aligns with the optical axis of the cage, ensuring precise positioning. The goniometer is secured to the cage adapter using two standard M3 screws and nuts. The cage adapter can be locked into place along the cage rods by tightening two M3 set screws on either side; holes must be tapped for this purpose. Three bottom holes with 3 mm diameters are provided for adjusting the locking screw.
