The SL 100 is intended for spectral decomposition of radiation in the 360 to 1100 nm range, selection of a specific spectrographic bandpass and its registration with a CCD-, ICCD-,diode arrays-(or other) photoelectronic detector

  • The SL 100 is implemented as a horizontal optic configuration with cemented double-lens objectives used as a collimator/camera objective
  • Features

    • original optic schematic
    • achromatized and antireflection-coated lens objectives
    • no distortion
    • high optical throughput, wide field of view, planar focal surface with small focal length
    • very low stray light
    • very simple procedure for matching the spectrograph focal plane with the surface of detector pixels
    • designed to be easily mounted
    • compactness and low weight
