Siskiyou diffraction grating mounts support reflective and transmissive optics

GMx series mounts combine rotational adjustment of square components in all three orthogonal axes, and support both reflective and transmissive optics. They can hold 12.5, 25, and 50 mm square optics of any thickness >2 mm and offer up to 8° of total rotation in each axis, with a resolution down to 3.2 arcsec.
