Thorlabs kinematic mirror and lens mount
Similar to KM100
Description: nice lens kinematic mount removed from High School laser lab. Measures: 2x2" (51x51mm). The lens holder is a bit smaller, around 49x49mm. It holds 26,2mm and smaller lenses (lenses smaller than 23,7mm would need a longer locking screw and use the mount in horizontal position). Lenses seat in a couple of plastic little bases that protrude a little bit and they are held in place through an allen screw ended in plastic tip (which avoids scratching or damaging expensive optics). The big hole is Ø 31,82mm (around 1,25"). It has 8-32 imperial mount thread (for breadboard or other components), similar to M4 but bigger pitch. Screws are metal 100 TPI. High quality.
Condition: normal usage marks. Nice working condition.
Note: these items have been de-greased, cleaned, re-greased (with special oil, better than original grease) and checked for missing or damaged parts. Then tested and verified ok. Good functioning is garanteed.
Issues: some marks of normal usage here and there.
