    Default GM20s with mounts and collimators

    I have GM20s in mounts with mirror arms. The mounts were designed to shoot the beam straight up, but the GM20 can be rotated 360 degrees in the mount so you can use them as needed. I also have 4X collimators that were part of a beam table. The collimators have 25 and +100 plano BB AR coated lenses from Edmond sci. They are topped with an MM-1 style mount that also rotates 360 for coarse aiming.

    I am selling the GM20s with the mount and mirror arm.

    The collimators include all hardware pictured including the 6 mounting posr and the top gimbal with mirror.

    I am asking $75 obo for the GM20 and $50 obo for the collimator.
