Modular Mounts
M-SWITCH
The M-Switch series of adjustable, modular mounts are designed to redirect a horizontal interferometric set-up to a vertical one. This vertical orientation can help reduce distortion effects commonly found from clamping, and reduce alignment time. There are 4 primary versions of hardware designed to enable testing of mirrors, windows, lenses and lens assemblies. Holding of the part under test can be done with a variable 3 arm mount (for flexibility) or our kinematic mount (for high volume). Reference mirrors can be supplied with a variety of flatness and coating specifications to match your application needs.
