Bandpass, Longpass and Shortpass Filters are high-precision optical components that selectively transmit/block specific wavelengths. Made of high-purity materials (germanium, sapphire, silicon) with professional dielectric coating, they feature high transmittance, deep blocking and stable performance, meeting global customers' diverse needs.
