Dichroic filters are for LED applications
LED ColorDichroic filters efficiently reflect and transmit random polarized light from individual high-brightness LED sources. Applications range from projection-display illumination optics to use in solid-state lighting and instrumentation. The spectral separation between highly transmissive and highly reflective wavelength ranges is reduced compared to typical spectral characteristics of standard dichroic filters/mirrors for random polarized light.They are coated on flat borosilicate substrates with a standard thickness of 0.7 and 1.1 mm. Other glass types as well as other thickness values are available upon request.
