Fluorescence filter set for four-colour imaging
Semrock
Quad-band fluorescence filter
Semrock has announced the first complete quad-band fluorescence filter set for simultaneous four-colour imaging by eye or with a colour camera using broadband illumination.
The DA/FI/TR/Cy5-A quad-band set is comprised of three high-performance, hard-coated optical filters.
The excitation and emission filters each have four high-transmission passbands and are said to feature excellent out-of-band blocking and a matching beamsplitter with four precision edges.
The FF01-387/485/559/649-25 quad-band exciter includes a high-transmission passband at ultraviolet (UV) wavelengths, in addition to three longer-wavelength precision passbands.
The entire filter set is constructed with Semrock's hard ion-beam-sputtered technology so the filters won't burn out, even under intense UV irradiation, and are virtually impervious to humidity and temperature-induced degradation for permanent performance.
