Product Announcement from PLX Inc.
A new innovation in Hollow Retroreflector technology, the PLX USHM (Ultra Stable Hard-Mounted Retroreflector) is a self-compensating mirror that is totally insensitive to position and movement, such as tilt or rotation. Parallel incident light that hits the USHM will be returned with great accuracy to the light source, regardless of the USHM's physical orientation.
The USHM is an improved hard mount solidly connecting the Retroreflector to the next assembly.
The USHM is vacuum compatible and can be positioned about the permanently connected post in any orientation, providing greater freedom for different mounting configurations.
Stability and Accuracy
The USHM offers properties, which enables it to perform well in critical applications, such as military, aerospace, or any OEM requirements. It is especially well suited for interferometers where high stability of the OPD and the concentricity of the apex with respect to the mounting thread are critical requirements. USHMs can also be provided in matched pairs for better modulation.
