Unmatched Performance

The Classic Suprema is the industry's best performing modular optical mount, setting the standard for stability and adjustability in today's demanding research and industrial applications. Suprema mounts provide the feel necessary to tune the most sensitive set-ups and the stability to hold that position better than any other mount on the market.

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

All 1" (25.4 mm) and 2" (50.8 mm) Suprema mirror mounts are made with super hard 10 µ-in. precision-polished tungsten carbide kinematic pads ensuring a highly stable kinematic mechanism.

The Stainless Steel Advantage

All Suprema mirror mounts are made from stainless steel making them the most stable and easiest to align.  Stainless steel is 3X stiffer than aluminum so it flexes significantly less allowing easier alignment.  Stainless steel's coefficient of thermal expansion is lower than aluminum making it more stable during temperature fluctuations.  Stainless steel makes Suprema the flag ship of Newport’s mirror mount offering.

Replaceable Actuators

The Suprema SU100 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. Please see our recommended actuators below.

Locking Adjustment Screws

Suprema Classic 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.
