The IR LUPI (Laser Unequal Path Interferometer) operates at a

wavelength of 3.39 micrometers and features an internal He-Ne

IR laser as well as an integral collinear visible alignment laser.

The IR LUPI is the ideal instrument for testing mid-wave infrared

imaging systems of any size or complexity.

*Integrated aperture zoom, focus, and panning provide optimized

  viewing of the fringe pattern.

*Optional objective lenses convert the output to a diverging beam

  for testing camera, lenses, and other imaging systems.

*An optional Translation Base provides extended 3-axis positioning

  travel offering unprecedented positioning flexibility.

*Internal reference mirror features selectable effective reflectivity

  values of 90%, 40%, and 4% to match the optics under test,

  available at the turn of a knob.

The RAD-900 Infrared Radiometer makes precise measurements of

radiometric temperature and spectral radiance.  It operates in the

both the MWIR and LWIR bands and may be used to carry out

both 1D and 2D source radiance measurments when installed on

the ASB-920 Angular Scan Base.   Through its calibration, the RAD-

900 provides traceability to national standards and to the

International Temperature Scale. Most thermal Target Generators

are factory calibration to provide precise physical temperature

differences between their forground and background, but the

reflective or refractive collimators with which they are typically

paired attenuate the radiation from these target generators,

making the thermal contrast of the target appear smaller than

the physical difference. The RAD-900 provides an accurate

means to perform a radiometric calibration for a thermal target

generation system by accurately measuring the radiometric

temperature difference of the target as a function of the

physical temperature difference.  In this role, it is an  essential

component of a complete thermal imager testing laboratory.
