525/50 nm BrightLine® single-band bandpass filter

Semrock Logo

Individual fluorescence bandpass filters that have been optimized for use in a variety of fluorescence instruments. All thin-film, hard-coated construction for unsurpassed performance and reliability.

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.
