The long wavelength channel detector for the ISOCAM camera

The European satellite ISO is a scientific satellite devoted to the observation of the Universe within the 2.5-200 micron wavelength range. Among the four scientific instruments of ISO's focal plane, the ISOCAM camera is designed to provide 32*32 pictures in the 2.5-5.5 mu m and 4-17 mu m bands. The authors describe the ISOCAM camera and the long wavelength channel (LWC) detector and present experimental results obtained on the LWC detector around the liquid helium temperature (4.2 K). The responsivity, noise equivalent power and flat field precision are presented in the form of charts which give an idea of the spatial dispersions observed.<
