ISOCAM, the camera of the Infrared Space Observatory, will make images of the sky in the wavelength range 2.5 to 17 microns. The camera was integrated with the telescope and the three other scientific instruments in January 1994 and since then three sequences of tests have taken place: a set of tests meant to measure the straylight in the cryostat; a complete set of tests (with the integrated payload module alone) to measure the performances of the camera; and the same set of tests, but with the fully integrated satellite (payload plus service modules). In the last two cases, the results of the tests were nominal and within a few percents of those obtained in the ISOCAM calibration facility. But in all three cases, the ISOCAM pupil imaging lens was useful in detecting and identifying heat sources or leaks within the cryostat, thus taking its first images through the ISO telescope. |
