The new version of our Model 106irVIS Dual-Wavelength Fizeau Interferometer operates in two modes: Infrared or Visible -- switch selectable. The  Model 106ir features a fused silica collimator and includes a Transmission Flat with standard bayonet mount (1/20 wave measured at 632.8 nm). The interferometer utilizes as single SWIR camera for greater simplicity as well as improved contrast and sensitivity. Offered in both Standard Resolution (320x256 pixels) and High Resolution (640x512 pixels) the Model 106irVIS features a fused silica collimator and includes a Transmission Flat with standard bayonet mount (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.

The Model 106irVIS utilizes our Frequency-Shifting 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, the Model 106irVIS is equipped with a 2.93 GHz Computer including a 22-inch TFT flat screen monitor.
