Dual Bandpass Filter | 500.7nm&656.3nm, FWHM 3±1nm, 2.0mm Thickness
The OPTOStokes dual bandpass filter is a high-precision optical component engineered for simultaneous transmission of two discrete wavelengths. It provides transmission greater than or equal to 80 percent at both 500.7nm and 656.3nm, with an ultra-narrow FWHM of 3±1nm and exceptional high OD blocking across 300–1050nm. This 2.0mm thick filter is designed for 0 degree angle of incidence, delivering stable and consistent performance for demanding scientific and industrial applications.
