These mirror mounts are designed for use in vacuum systems with a conflat CF 2.75 flange and can accept 1.0" OD optics with a variety of thicknesses (0.07" - 0.50") with or without a small wedge (< 2°). This mount is configured for applications where back reflection or etalon effects must be minimized with a 0.5° wedge between the optic and mounting surfaces and includes a 1" quartz window with a 0.5° wedge. The window is held in place with a non-marring high temperature silicone seal on a knurled aluminum knob for easy removal and replacement. These red anodized mounts may be heated and baked out up to 210 °C. Mounting screws are included for connections to both tapped and through-hole conflat flanges.
