Paper Abstract

A fiber linked spectrograph is described which was built for use at astronomical telescopes with apertures of less than 100 cm12,13. The link between the telescope and the spectrograph was made by means of two single step index glass-on-glass fibers with g core diameter of 6,3 μm. The transmission of a 10 m fiber link lies between 65 % at 4000 Å and 98 % at 8000 Å. Reciprocal dispersions between 27 Å/mm and 370 Å/mm can be realized. The best resolution at 27 Å/mm is 0.5 Å The spectrograph is equipped with an intensified TV ca-mera guiding system for remote operation.
