Mirror Mount, Suprema^®, Clear Edge, 2.0 in., 3 254-TPI Knobs

The SN200-F3K-254 is a stainless steel mount for 2-in (50.8-mm) diameter optics and is sold with three 254-TPI adjustment screws for precision pitch/yaw positioning as well as linear translation. This Suprema^® mount is designed to be more compact than other mounts of its size, allowing unencumbered access to the edge of the mirror. This precision mount utilizes micro-polished carbide pads which enable smooth, low-friction adjustment and outstanding stability. The three adjustment screws with knob have tip and tilt adjustability over a range of +/- 7 degrees. 254-TPI adjustment screws provide a 60% sensitivity advantage over the standard adjusters. Convenient 8-32 (M4) counterbored clearance holes provide quick, precise, secure and stable mounting. 

The Clear Edge Advantage

With the Clear Edge design, beams can be reflected from one mount to another at smaller incident angles (Φ) taking less space between the mounts (d). Clear Edge Mounts are also ideal for compensating for pulse dispersion effects through multiple reflections on Chirped Mirrors.

In-Process Heat Treatment

Every Suprema mount is heat treated as part of the fabrication process. Heat treating relieves the build up of fabrication stresses which improve the overall stability of the mount.

Precision Polished Carbide Pads

Suprema SN100 series mirror mounts are made with super hard 10 µ-in. precision-polished tungsten carbide kinematic pads ensuring a highly stable kinematic mechanism.

Locking Adjustment Screws

Suprema Clear Edge Low-Drift Mirror Mounts use a Flexure Lock built with an AJS bushing. Flexure Locks exert a tangential force on the screw to prevent rotation.

Replaceable Actuators

The Suprema SN100 and SN200 mount design allows actuators to be removed and installed with ease. Loosening the lock nut lets the actuator gently slide out from the mount enabling reconfiguration for specific applications. This industry-standard 9.5-mm bore allows many different types of actuators to be used with these versatile mirror mounts. Suprema mounts are compatible not only with standard actuator screws, but also with micrometers, Allen-key adjusters and differential micrometers.
