The design and performance of a new 1024-element PtSi IR linear array and detector head available from EG&G Reticon are described. The self-scanned Schottky barrier detector array provides a 1.1 to 5.0 micrometers spectral response, 60% fill factor, 25 micrometers pitch and 100:1 slit-like aspect ratio for efficient coupling to laboratory spectrometers. Pixel-to-pixel non- uniformities of 0.4% rms and saturation charge levels of 9 picocoulombs are achieved. The LN2-cooled detector head used to house the array features a fast focal ratio, short window-to-detector separation and quasi-standard mounting flange. Both analog video and temperature sensing outputs are provided. Timing may be internally or externally controlled. In the former mode, only +/- 15 VDC and +5 VDC power inputs are needed. In the latter mode, external clock and sync inputs as well as power are required. The sensor, dewar, and coldshielding is described; as well as the analog, digital and temperature sensing electronics. A discussion of system-wide performance data and technical specifications concludes the review.
