WebMulti-layer dielectric optical filters are a passive, robust, highly selective, and economical means of providing wavelength selectivity to these optical sensor/detectors. Optical filter technology has seen an evolution in durability, filter shape complexity, and cost to address needs in the VIS/NIR/SWIR wavelength range. WebThe bandpass filter alone is composed of a dielectric stack that is ~4.5 µm thick and provides blocking in a relatively narrow wavelength range. If this filter is deposited on UG5 glass that is 3 mm thick, the spectrum is shown in green and shows moderate (OD2) blocking over the visible range with some deeper blocking in spots.
