The getLight 5090 SET has an innovative optical design, in which a dichroic beam splitter is integrated to give a much more balanced spectrum from 200-2000nm by filtering out the alfa peak. The result is a smooth spectrum with an output-power lower by a factor 5 than for the standard version, but dynamic range is rising by a factor of 20.

There is an integrated TTL-shutter and filter holder for filters of up to 50x50x6.5 mm implemented.
