The
Model
155ir is a 4-inch aperture Phase Fizeau interferometer with
a fused silica collimator and a reference surface which is flat to 1/20
wave (measured at 632.8 nM). Operating at 1550 nM wavelength, the Laser
Diode source together with our unique dithering system, produces a sharp,
speckle-free image.
