An intensified UV imaging system covering the wavelength range 120 to 330 nm has been built and tested for space flight. A six-position fil-ter wheel divides the range into four narrow bands of interest, provides an ND1 filter for increased dynamic range, and provides a calcium fluo-ride window for maximum sensitivity and good rejection of Lyman al-pha. The optical path includes a reflective telescope, a cesium telluride image intensifier, a fiber-optic reducer, and a 380 by 488 pixel CCD sen-sor. The overall field of view is approximately 2.4° x 1.8°, with an angular spatial resolution exceeding 125 μrad. The system includes digitiz-ing electronics, associated memory, and a microprocessor-controlled AGC system. The maximum sensitivity of the system to a point source ex-ceeds 20 photons/cm2-s in the photon counting mode; with the use of the AGC and ND1 filter, the dynamic range exceeds 107.
