Two-D array detectors are one of the key components of the instruments being built for the four ESO 8-m telescopes, the VLT project. Three optical and two infrared instruments are under construction. One faint object imager and multi-slit spectrograph to operate in the spectral region 350–1000 nm (acronym FORS) is based on a 20482 high-efficiency CCD. A two-channel echelle spectrograph to work in the 300–1000 nm region (UVRS) is built around a mosaic of 20482, 15 μm CCDs. A multifiber, new spectrograph is based on a 4096 × 2048, 16 μm CCD. The two infrared high-resolution instruments, one imager/long-slit spectrometer (ISAAC) and one high-resolution camera are designed to work with adaptive optics and in the speckle mode (CONICA). Both are designed to incorporate IR arrays up to a format of 10242 and will work in the spectral region of 1–5 μm. The main properties of the instruments and of detectors are presented and their close interdependence is illustrated.
