Kinematic Optical Mirror Mounts Star Series SR100

The SR100 is our standard mirror mount size, most useful for 1″ optics. Manufactured from special stress free Aluminium, these mounts offer the highest quality and stability. Also available with thicker back plates, and Stainless Steel M8 adjusters, the High Stability SR100 variant is ideal for the most demanding applications.
As with all our mirror mount series there is the option of using the adjuster head or an allen key for fine adjustments of the mirror mount. The mirror mount is available with 2 or 3 adjusters, the 3-adjuster option enabling precise horizontal positioning of the optic. Very precise adjustment of your optical component is possible because of the 170TPI (turns per inch) screw threads.
