Since grease can migrate, causing long-term creep, our New Focus mounts are exclusively fitted with thread-matched adjustment screws which take almost no grease.  The result is actuators that have very smooth, wobble-free movement, high precision, and mounts with exceptional long-term and thermal stability.
 

To address the needs of our OEM customers, we offer a commercial version of our most popular mount, 9805-K. Ideal for laboratory use, as well as for building into your products, this mount features sapphire pads for excellent adjustability and durability, extra-stiff springs and actuator locks for long-term stability, and two mounting holes per side, minimizing rotation when you secure the mount. The optic can be secured either by a nylon-tip setscrew or by a retainer plate for reduced wavefront distortion.
