Hi Kyle,

If your design will allow the extra height, I’ve mounted my Kinematic mounts to a multi-axis platform.

The tube lenses are 200 mm focal length Nikon lenses and are mounted in adapters for Thorlabs 2" optomechanics with SM2 external threads (https://www.thorlabs.com/thorproduct.cfm?partnumber=SM2A20). The adapters are currently mounted into 2" kinematic mounts supporting x- and y-translations and attached to the table with a standard post and post holder.

Has anyone found a satisfactory way to mount and align these lenses to all five degrees of freedom? Unless I am mistaken, most of the major suppliers only make 4-axis kinematic mounts for 1" diameter optics.
