SPECTROGRAPH SLO100M


SL100M_Gr.tif.png        

Imaging spectrograph SLO100M with F-number of 3.3 and focal length of 100 mm uses a horizontal-symmetric configuration with two objectives.

To provide wavelength scanning SLO100M Spectrograph is furnished with a micrometer screw.

Basic configuration includes “C-mount” output flange.

There are two models of SLO100M spectrograph:
  • SLO100M is optimized for VIS-NIR spectral range (360 - 1 100 nm)
  • SLO100M-UV is optimized for UV range (200 - 600 nm).
