Paper Abstract

The advancing state-of-the-art for long-wavelength infrared (LWIR) sensors has created a need for increasingly sophisticated low-background sensor test facilities. A new low-temperature, low-background, optical target collimator system has been designed and built to meet these new sensor requirements. The design incorporates a Ritchey-Chretien off-axis optical system with an effective focal length of 500 in. and an aperture of 25 in. This optical system provides excellent high-resolution, diffraction-limited performance for wavelengths of 0.76 μm and longer, both on-axis and off-axis. It has a useful field of view in excess of ±0.5 deg. Two scan mirrors in the collimated beam provide a beam steering capability of 6 deg.
