General purpose mirror mounts don’t always do the trick. Optical Surfaces’ OS-Z mirror mounts were developed to support off-axis parabloid, spherical and flat mirrors in a manner that allows overcoming a number of constraints imposed by general purpose mounts. Two key advantages include rapid alignment using an optional pre-alignment aid and the ability to routinely accommodate wedge back and parallel back mirrors. Constructed in black anodized aluminum, six models are available and range in size from 90 mm to 250 mm. Optical Surfaces Ltd.
