484/561 nm BrightLine® dual-band bandpass filter

Semrock Logo

Individual multiband fluorescence bandpass filters that utilize Semrock’s patented single-substrate construction. These filters have extremely high transmission, steep and well-defined edges, and outstanding blocking between the passbands. All thin-film, hard-coated construction for unsurpassed performance and reliability.

BrightLine emitter for CFP/YFP imaging channels optimized for Lumencor CELESTA light engine® utilizing 445 nm & 518 nm wavelengths.

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.
