Flexure Mirror Mounts / FM

This stainless steel mirror mount has a compact and simple structure with three plates connected by a plate spring, and is optimized for use in equipment integration.

FM is a block type and can be installed in two directions on the front and back surfaces, while FM-L is a bracket type and the mirror mounting surface can be placed perpendicular to the installation surface.
The FM allows the mirror to be mounted on either the surface plate or the back plate, and the user can choose to operate the mirror adjustment from the reflective side of the mirror or from the same direction as the mounting surface.
Two M3 screws are used to fix FM and FM-L.
The mirror is held at three points on the side including the element holding screw with a resin tip to which pressurization is applied. There is also a 1.5 mm dia. hole for adhesive fixation.
Dia. 2mm positioning pin holes are provided on the front and back of the FM and on the bottom of the FM-L bracket.
