Narrowband filters are generally narrowband filters with a width at half height (FWHM) of less than 2nm, transmittance greater than 85%, and a cut-off depth greater than OD4. Indicators such as transmittance and cut-off range can be designed and plating according to customer needs. Center wavelength: 400-1100nm FWHM:1-2nm T peak: ≥85% (negotiable) Cut-off wavelength: 200-1000nm (negotiable) Cut-off depth: ≥OD4 (negotiable) Product size: specified by customer |
