The
Model
106ir is one of our new infrared Phase-shifting Fizeau Interferometers
utilizing a fused silica collimator with integral reference surface flat
to 1/20 wave (measured at 632.8 nM). A single mode diode laser operating
at 1060 nm is dithered to produce speckle-free live images on the computer
monitor. A CCD Camera provides resolution of 768 x 494 pixels.
