Interferometers
The Interfire 10.6 and 3-5 Interferometers use the Twyman-Green unequal-path design for testing IR materials at 10.6 µm or 3 to 5 µm, respectively. The instruments integrate a collinear visible HeNe for alignment. The system measures wavefront aberration of thermal imaging lenses, optical homogeneity of IR materials, and the flatness of optical surfaces.
