Avantier Inc.
Bandpass Filters Bandpass Filters. Bandpass filters are optical filters designed to transmit a defined spectral band while blocking or attenuating wavelengths outside that range. Depending on the application, the passband may be narrower than 1 nm for laser, fluorescence, or spectroscopy systems, or broad enough to span tens to hundreds of nanometers for imaging, sensing, and illumination. Bandpass filters typically use thin-film interference coatings on substrates such as optical glass, fused silica, sapphire... (read more) -
