Description: removed from High School lab (laser R&D). This is a 2x2" (50x50mm) lens mount with pedestal and pole holder. With this pole and holder total variable height is 127-155mm (28mm travel). Lens seems like new. I don't know focal length but it is PCV (plano-concave) negative lens and it "sees" 60mm in a ruler placed @ 100mm distance (aprox. measures). It has 18mm clear diameter with the included retainer. Holder has a locking allen screw to keep pedestal in place. Lenses are kept in place in a SM1 receptacle through a retainer ring. This mount would happily accept 19-26mm Ø lenses.
Condition: normal usage marks. Lens and mount are in excellent condition.
