Abstract:
On February 6, 1992 at the ESO than on the existing large ESO tele- and to allow accurate polarimetry, an Headquarters in Garching the FORS in- Scopes. FORS 1 and 11 will therefore be all-dioptric design was chosen. Its prinstrument project for the ESO Very Large something like the workhorses of the cipal layout was derived by ESO opti- Telescope was publicly started with a VLT, and their duplication will save con- cian B. Delabre on the basis of the exkickoff meetina. FORS, the Focal Re- ~tructionC osts and later simplify Opera- perience gained with EFOSC. ducer/low dispersion s6ectrograph, will be the first instrument built outside ESO to be installed at the VLT observatory. The idea for a set of general-purpose focal reducers for the VLT can be traced back to the recommendations of the ESO Working Group on Imaging and Low-Resolution Spectroscopy, published in VLT Report No. 52 (1986). The experience gained with EFOSCtype instruments at the 3.6-m telescope and at the Nl7 then led ESO to propose in the VLT Instrumentation Plan of June 1989 the construction of two dioptric focal reducer/low dispersion spectrographs for deep-imaging, low-resolution and multi-object spectroscopy. The Cassegrain foci were chosen for the instruments because of their high throughput, to minimize the amount of scattered light and to make them suitable for polarimetric observations. Following a Call for Proposals issued in 1990 a consortium composed of three German astronomical institutes (the Landessternwarte in Heidelberg and the University Observatories of Gottingen and Miinchen) was chosen in 1991 for the realization of the project.
