430nm Mid-Bandpass Filter | 30nm FWHM | Wideband T<1% Blocking
The OPTOStokes 430nm Bandpass Filter is optimized for high-efficiency signal isolation within the blue-violet spectrum. It features a controlled 30nm FWHM and guarantees transmission greater than 90 percent across the 420-440nm range. Crucially, the component provides robust wideband blocking, suppressing undesirable light with less than 1 percent transmission from 350nm to 1100nm to ensure high signal-to-noise ratio.
