Abstract

A fiber linked spectrograph is described which was built for use at astronomical telescopes with apertures of less than 100 cm^12,13. 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.
