The SX200-R-LH is a left-handed, rear-loading, stainless steel mount for 2-in (50.8-mm) diameter optics and is sold without actuators to allow the addition of customer-supplied actuators to the mount. The new stainless steel alloy gives a 38% lower Coefficient of Thermal Expansion (CTE).  The Suprema^® XTE also has an optically black finish to reduce stray light reflections.  SX200 mounts have superior adjustability and feel. Polished and lapped carbide pads enable smooth, repeatable motion. This mount can be configured for tip and tilt adjustability over a range of +/- 7 degrees. For 2 axis configurations, i.e. pitch and yaw adjustment only, the CP-0.5 pivot is required. Convenient 8-32 (M4) counterbored clearance holes provide quick, precise, secure and stable mounting. Suprema mounts are compatible with standard post and post holder systems for adjustable height and pedestal posts for a stable fixed height.
