 The Model 106irVIS is our new unique Phase-shifting Fizeau Interferometer that operates in two modes: Infrared or Visible-- switch selectable. The instrument features a fused silica collimator with integral reference surface flat to 1/20 wave (measured at 632.8 nM).  Two separate lasers are employed – 1064 nm single mode diode laser and a 635 nm single mode Diode Laser.  Both sources are dithered to produce speckle-free live images on the computer monitor.  A single Camera provides 768 x 494 resolution at both wavelengths. 

The Model 106irVIS utilizes EndoPhazeTM for hysteresis-free phase shifting.  Durango Universal Interferometry Software  allows the operator to achieve highly accurate and repeatable measurements at both infrared and visible wavelengths. In typical usage of a Dual Wavelength Interferometer, the operator can align his optical system and perform any necessary tip/tilt operations with the interferometer in VISIBLE MODE—greatly simplifying the procedure.

Featuring Zoom optics, with remote control of Zoom, Focus, Iris and Illumination intensity, together with the high resolution CCD camera, the Model 106irVIS is equipped with a 3 GHz Computer including a 22-inch TFT flat screen monitor.
