UV and Visible Wavelength Calibrated Filters
Wavelength calibrated glass optical filters
Wavelength calibrated didymium glass filters produce characteristic peaks that make it suitable as a reference material in the 300 to 900nm region for wavelength calibration.
Didymium wavelength calibrating filter
Wavelength calibrated filters are designated as WL 01.
WL 01 is equivalent to Schott BG 20 and Hoya V-10
