Scientific paper

The major optical components of the Very Large Telescope (VLT) being constructed at ESO (scheduled completion in the late 1990s) are briefly described and illustrated with drawings. The VLT is a linear array of four 8-m Ritchey-Chretien unit telescopes with unvignetted FOVs of 20 arcmin at the Nasmyth foci and 15 arcmin at the Cassegrain foci. An equivalent diameter of 16 m is achieved at the combined coude focus, and a closed-loop feedback control system is used to correct gravitational, thermal, wind, and vibrational effects on the unit telescopes. Consideration is given to the 175-mm-thick spin-cast Zerodur primary mirrors, the computer-controlled polishing process; the 150 axial primary-mirror supports, the active control algorithms, the secondary mirrors and their drivers, and the coude optics at the VLT combined focus.
