2.1.13. Module 6.2.2: Imaging optics adaption & filter
changing unit for RF measurement position
The lexsyg can adapt imaging light detectors based on charged coupled devices, in
particular an EMCCD based module (5.2.1) is available for spatially resolved measurements,
incl. single-grain measurements. Such detection units need advanced optical design for best
imaging quality within a chosen wavelength-band to be measured which is set by the optical
filters detection- window. Imaging units also work with PMT detectors and thus assure best
performance if a LEXSYG measurement chamber with automatically detector change is in
use.
