Paper Abstract

A spectrograph with collimator compensated camera chromatism (4C) is presented. It has the following advantages compared to classical designs: The camera is small, inexpensive, and can be easily exchanged. It is based on standard materials. Large aspheres are not needed for the lenses. It appears that there are no problems to scale up the design for beam diameters well over 0.5 m. The instrument is efficient and there is no vignetting. The long slit allows a large degree of spatial multiplexing.
