Features

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.

254-TPI Adjuster Version Now Available

The SU series mounts equipped our AJS 254-TPI adjustment screws are now avaiable. This ultra-fine adjuster provides alignment sensitivity as low as 1.5 arc sec, a 60% improvement over mounts having 100-TPI adjusters. Better adjustability means faster, easier alignment.

Test Data

Purpose:
Newport's thermal drift testing of mirror mounts has two purposes: (1) to measure the maximum deflection during a peak temperature shift (after a soaking period) and (2) to measure the shift in position after temperature cycling and return to initial temperature.

Method:
A mirror mount, with mirror installed, was securely fixed to a 1.5"-diameter solid steel pedestal post. This assembly was then placed inside of a climate-controlled environmental chamber and mounted to a stainless steel optical table.  Upon fastening to the table, the mirror mount was set to nominal and zeroed to set the initial position. Throughout the test, an independently thermally isolated CONEX-LDS Autocollimator was used to monitor the reflected beam position. After initial alignment adjustments, the mirror mount was left to rest for two hours to allow the internal kinematic forces to reach equilibrium. Then, the mirror mount was subjected to a 10°C increase in temperature for one hour through convection heating. After a thermal soaking period to ensure the mount is sufficiently heated through, the mirror mount was returned to its original temperature, completing a cycle. This temperature cycling process was repeated 10 times over the duration of 62 hours, with deflection during peak temperature and shift after the end of each cycle recorded.

SU100-F2K Thermal Testing Results

The maximum deflection of the SU100-F2K mirror mount during peak temperature was 7 µrad in pitch and 17 µrad in yaw, and the shift in reflected beam position after temperature cycling was < 1 µrad in pitch and < 1 µrad in yaw. This demonstrates the mount's excellent thermal properties. Further details are shown in the accompanying graphs.

SU100-F3K Thermal Testing Results

The maximum deflection of the SU100-F3K mirror mount during peak temperature was 15 µrad in pitch and 10 µrad in yaw, and the shift in reflected beam position after temperature cycling was < 1 µrad in pitch and < 1 µrad in yaw. This demonstrates the mount's excellent thermal properties. Further details are shown in the accompanying graphs.

SU100-F2K-254 Thermal Testing Results

The maximum deflection of the SU100-F2K-254 mirror mount during peak temperature was 36 µrad in pitch and 31 µrad in yaw, and the shift in reflected beam position after temperature cycling was < 1 µrad in pitch and < 1 µrad in yaw. This demonstrates the mount's excellent thermal properties. Further details are shown in the accompanying graphs.
