376/384/394/404/412.2/423.6/434.7/443.6/455/468/478 nm BrightLine® hendeca-band bandpass filter

Semrock Logo

Semrock designed an 11-band bandpass filter optimized to capture the peaks of formaldehyde emission over the 380 – 480nm wavelength range to improve the fluorescence signal. Formaldehyde is an ideal chemical for use in laser-induced fluorescence (LIF) when excited at 355nm. 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.
