SL 100 LENS SPECTROGRAPH
 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
