GM20's with Mount and Collimator

**Kirk** · 01-26-2011, 13:13

General Scannings GM20 with adjustable mount, and arm with first surface mirror. Also includes a 4:1 collimator with adjustable bounce mirror. These were designed for a fiber fed beam table. The beam was collimated by a short lens which kept the diameter small enough for a pick-off mirror, but had poor divergence. After the pick-off mirror, the beam shot up through a secondary 4X collimator and to a mirror on a gimbal for final aiming. These have had very little use and have been in storage for several years. I am selling them as components, with no base or drivers. All scanners have been tested and guaranteed to work. $125 per set OBO.
