Features

MFM Mounts are Designed for Industrial Applications

Newport’s MFM Series Mirror Mounts are specifically designed for “Set and Forget” OEM applications. They all have: 1) Compact geometry, 2) Hex key (knobless) adjusters to save space and prevent tampering. 3) Extra stiffness from stainless steel construction. 4) Adhesive wells for permanent mirror mounting.

Flexure Design Means Compact Size

With a flexure mirror mount, a spring-steel element provides the means for angular positioning. The double-duty ability of the flexure provides both guided rotation as well as the spring force, enabling a more compact design. 

Clear Edge Versions for Beamsplitting Application

Specially designed for beamsplitting applications, we now offer clear edge MFM series mounts which allow for plate beamsplitter to pass the transmitted beam at 45 degrees through the edge of the mount. Welded construction, stiff flexure pivots, and precision adjustment screws with locks provide excellent mechanical stability. These mounts are designed for 0.75 in. optic and offered in right- and left-handed, imperial and metric versions. They can be mounted to an optical post or table using the matching base (MFM-075CB or M-MFM-075CB ), or require a custom base for OEMs.

LaserClean™ Versions

Many laser-based applications require extra care to reduce volatile organic compounds (VOC) and ensure added cleanliness. VOCs and other contaminates can deposit on to optical surfaces causing degradation in output power, beam quality, and wavelength. Newport now offers certain Opto-Mechanical components that are specially prepared with clear anodize, nickel plating or stainless steel materials, special lubrication and V6 vacuum-level cleaning. Products are packaged in Class 1000 (ISO 6) cleanroom grade bagging material and then double-bagged for further cleanliness precautions. We call these products, LaserClean™. The LaserClean version of MFM series flexure mounts are also available.

A High Resolution 100-TPI Option

All MFM Industrial Flexure mirror mounts are available with either 80-TPI or 100-TPI adjusters.  The 100-TPI thread (available in the –HR versions) provides a 25% increase in adjustment sensitivity meaning more accurate alignments.  The graphic below shows the difference between an 80-TPI thread and a 100-TPI thread.  Note that while the pitch is distance between threads, it also can be thought of as the distance the adjustment screw will travel in one complete rotation.

Collection of OEM Mirror Mounts

The newest and best performing OEM mirror mounts come from Newport. We've focused on incorporating key features for industrial applications into each mount including alignment pin slots, adhesive wells and actuator locks.  Click the video link here to see the industry's most cost-effective, compact, and stable mirror mounts.

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.

MFM-050 Thermal Testing Results

The maximum deflection of the MFM-050 mirror mount during peak temperature was 10 µrad in pitch and 7 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.

MFM-100 Thermal Testing Results

The maximum deflection of the MFM-100 mirror mount during peak temperature was 8 µrad in pitch and 6 µrad in yaw, and the shift in reflected beam position after temperature cycling was < 2.5 µrad in pitch and < 1 µrad in yaw. This demonstrates the mount's excellent thermal properties. Further details are shown in the accompanying graphs.
