High Definition Spectrum Analyser - HDSA
The HDSA is designed to analyse emission spectra of any complexity, while processing
the entire spectral range from 400 nm to 900 nm at once.
The fundamental principle of
HighFinesse products
"no moving optics" applies to the HDSA as well,
so cw- and pulsed
light sources can be measured.

Sample measurements:
Typical measurement of the spectrum of a gas discharge lamp.
The HDSA resolves lines over the entire visible spectral range.
