The OneTouch™ mirror mount is one of the simplest and most convenient mirror mounts ever made. Simply touch the spring-loaded button on the side of the mount, insert the mirror, release the button and the mirror is held securely in an adjustable mount. To remove the mirror, reverse the procedure. Cut-outs in the side of the mirror mount make it possible to avoid touching the mirror surface. A slight non-circularity in the mounting aperture ensures that the mirror is always kinematically seated and allows for a variation in diameter to accommodate both inch and metric diameters. The mirror surface is normally located above the slotted mounting hole. (This is useful if you need to rotate the mirror mount as the mirror surface will not move away from the beam during rotation.) Two additional 1/4 inch clearance mounting holes provide for permanent mounting when necessary. Fine pitch 100TPI (0.25mm) screws provide stable and controllable adjustment in two perpendicular axes of tilt.
