455nm High-Transmission Bandpass Filter | 25nm FWHM | T<1% Blocking
The OPTOStokes 455nm Bandpass Filter is designed for applications demanding precise spectral isolation in the blue light region. Featuring a controlled 25nm FWHM, it achieves peak transmission, greater than 90 percent, across the 450-460nm passband. This filter provides superior performance by blocking greater than 99 percent of light (less than 1 percent transmission) across the critical 350-1100nm range, maximizing signal-to-noise ratio in sensitive systems.
