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.
