The dramatic reduction in the stray light levels of a double monochromator compared to that of a single monochromator make it an essential tool in demanding spectral measurements.

The MCG990 is a compact 100mm focal length monochromator with two concave holographic gratings, covering the spectral range 200 - 800nm.

The monochromator can be supplied with a stepper motor and drive for PC or remote control, internal filter wheel and drive for shuttering and order sorting.

A range of accessories is available including cooled photo multiplier detectors, silicon detectors, light guides, arc lamp sources and integrating spheres.
