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.
SN100C-F3K Thermal Testing Results
The maximum deflection of the SN100C-F3K mirror mount during peak temperature was 13 µrad in pitch and 8 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.
SN200-F2K Thermal Testing Results
The maximum deflection of the SN200-F2K mirror mount during peak temperature was 30 µrad in pitch and 32 µrad in yaw, and the shift in reflected beam position after temperature cycling was < 2 µrad in pitch and < 1 µrad in yaw. This demonstrates the mount's excellent thermal properties. Further details are shown in the accompanying graphs.
SN200-F2K-254 Thermal Testing Results
The maximum deflection of the SN200-F2K-254 mirror mount during peak temperature was 40 µrad in pitch and 30 µrad in yaw, and the shift in reflected beam position after temperature cycling was < 3 µrad in pitch and < 8 µrad in yaw. This demonstrates the mount's excellent thermal properties. Further details are shown in the accompanying graphs.
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.
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.
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.
Precision Polished Carbide Pads
Suprema SN100 and SU100 series mirror mounts are made with super hard 10 µ-in. precision-polished tungsten carbide kinematic pads ensuring a highly stable kinematic mechanism.
Front- and Rear-Loading Options
The Suprema Clear Edge Low-Drift mounts are offered in both front- and rear-loading versions. Installing a mirror from the front is more convenient, which can be useful when replacing mirrors without having to disrupt an optical system setup or remove its components. Rear-loading a mirror guarantees that the reflective surface will be flat on the face of the mount irrespective of the mirror's thickness. (All rear-loading mounts are also left-handed for this product family.)
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. Please see our recommended actuators below.
254-TPI Adjuster Version Now Available
The SN series mounts equipped our AJS 254-TPI adjustment screws are now avaiable. This ultra-fine adjuster provides improved alignment sensitivity, enabling faster and easier alignment.
| Model | Adjuster | Sensitivity |
|---|---|---|
| SN100C | 127 TPI | 3.0 arc sec |
| SN200 | 100 TPI | 3.8 arc sec |
| SN200-254 | 254 TPI | 1.5 arc sec |
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.
