BP475nm Bandpass Filter | CWL 475nm, FWHM 18nm, High Transmission

The BP475nm bandpass filter is a precision thin-film optical component engineered for accurate spectral control in demanding optical systems. With a center wavelength of 475nm and a narrow 18nm full-width at half-maximum (FWHM), this filter delivers average transmission over 90% across the 470–480nm passband, while providing robust out-of-band rejection from 350nm to 1100nm with optical density greater than 2. As part of OPTOStokes’ comprehensive portfolio of bandpass filters, it is fabricated with advanced dielectric coating technology to ensure long-term stability and consistent spectral performance across varying operating conditions.
