LED-based light engines are steadily replacing traditional mercury, metal-halide and xenon light sources in fluorescence microscopy. As the spectral output of LED-based light sources differs from that of traditional sources, optical filter sets which were designed to take advantage of the peaks of the traditional sources, may now be sub-optimal for use with LED-based light engines. Semrock is now offering fourteen sets in single-band, full Pinkel & Sedat multiband configurations designed to be spectrally aligned with the excitation output of the most popular LED light engines on the market today.
