Fick Observatory Spectrum Scanners

Three low-dispersion (15 - 50 Å/mm)^-1 spectrum scanners have been developed at Fick Observatory as instrumentation for small telescope research and teaching activity. The two plane grating spectrometers and one holographic grating instrument have been employed on telescopes ranging from 7.6 to 61 cm aperture, generally with f/5 to f/8 configurations.
