403/95 nm BrightLine® Full Spectrum Blocking single-band bandpass filter

Semrock Logo

BrightLine® Full Spectrum Blocking single-band bandpass filter has been optimized to provide extended blocking down to UV wavelenghts (250nm) and up to the near infrared (NIR) and paired with a combination of VersaChrome Edge™ tunable long-wave-pass (TLP) and tunable short-wave-pass (TSP) filters to custom bandpass filters as narrow as sub 5 nm FWHM or as wide as 12% of the center wavelength throughout the visible and near-infrared wavelength range.

Note on spectral plots:
In the past, each shipment has included a spectral plot for every filter and every lot code in the shipment. In an effort to be more eco-friendly, we will no longer be including these plots with each shipment. If you require spectral plot data, please see here for more information.
