We have developed a 4 × 8 array of stressed Ge:Ga detectors. This array detector has a high density format of entrance pupils so that we can minimize the size of the camera optics. The cutoff wavelength of the detector is about 170 μm, and the detector's NEP is better than 1016 W Hz−1/2. We are going apply this array detector to balloon-borne astronomical observations. Furthermore, we are developing this detector into a 5 × 15 array detector that will be placed onboard the IRIS satellite to be launched in 2003.
