Infrared Interferometer

The Interfire II 3-5 infrared interferometer from !%Precision Solutions%! operates in the 3- to 5-μm region of the spectrum and can be used for performance testing of infrared materials and optical systems. Suitable for measuring wavefront distortion through IR systems and components, the device can evaluate high-specification lens assemblies to produce interference fringes that indicate the degree of aberrated performance. It features an accuracy of λ/20 and repeatability of λ/50.
