Filter wheel

Filter wheel including suitable filters, which are optimized for maximized luminescence light collection and maximum suppression of scattered light (OSL, PL) and thermal noise (TL), recommended as minimum configuration to perform optimized TL/OSL/RF analyses in dating and other applications.

  • Optics designed for high-efficiency light collection for PMT luminescence measurements

  • Programmable change of detection window (filter change min. 300 ms ... max. 3 s) during measurement

  • Malfunctions are software protected, including PMT damage protection during measurement

  • Optimized filter-sets for all main quartz or feldspar mineral luminescence emissions and for other materials/applications are available

  • Filter sets (interference, color-glass optical filters) optimized for largest transmission of individual wavelength bands and best blocking of stimulation light (OSL) and/or thermal noise (TL, blackbody radiation)

  • A filter wheel has 6 position and each position with 6.5 mm filter-space. 15 measurement functions are included (more information are available on request)
