Shanghai North Optics offers Bandpass Filters for Biochemistry Analyzers, Narrow Bandpass Filters for Enzyme Labelling Instrument, Narrow Bandpass Filters for Polarimeter, Fluorescence filters, Ultra-Violet (UV) Narrow Bandpass Filters and High Transmission Narrow Bandpass filters made from Colored Glass bonded with BK7 or Fused Silica (the glass we sourced are equivalent to that of Hoya). Exceptional optical performance is achieved utilizing the dielectric coating technique, furthermore, by doing so, the dependence of the optical performance on the thickness of the substrate is mitigated, so ultra-thin thickness can be realized, allowing compact integration, for instance, into a camera. Since no absorptive colored glass is used as the substrate material, the filter has good physical stability and is not prone to mold or fogging.

The narrow bandpass filters on this page feature a wide transmission central wavelength range of 700-10500nm, from Ultra-Violet (UV) to Visible (VIS) spectrum, and various options of bandwidths. Dozens of mounted stock modules with a diameter range of 6-25.4mm, and hard coatings are for choosing. We also provide custom bandpass filters tailored upon request.
