Description:
The University of California at Santa Cruz and the NASA Ames Research Center have developed a mid-infrared Si:Ga 128 x 128 array camera. The camera has been used on several flights on the KAO to obtain data in the mid-infrared wavelength (4-8 micron) range. At the f/17 bent Cassegrain focus, the pixel spacing is 1.6 arcsec, resulting in a FOV of 3.4 arcmin. The bandpass of the camera is determined by a set of 4 fixed filters and a 4-8 micron CVF. Camera performance of 92mJy/square arcsec/minute has been achieved, but is far from optimal. Realistic improvements to the camera and pointing stability on the KAO in the near future should increase the camera's sensitivity on future flights by 5-10x.
