Red-Bandpassfilter RTR SP for 600–750 nm

Dielectrical narrowband red Bandpassfilter for elimination of undesired radiation on receiver photodiodes

Red-Bandpassfilters SP are used in various optical sensor applications for blocking both ambient visible and NIR wavelength range while selectively transmitting signal light of a specified visible spectral range (e.g. red) for sensing application. Bandpassfilters are key components to achieve very high signal to noise ratios in optical sensing or distance measurements. Materion Balzers Optics Red-Bandpassfilter SP based on proven sputtering technology do not use colored glass substrates but clear glass substrates, which allow components to fulfill EU RoHS directive demands.
