This set is designed to take advantage of the superior resolution, sensitivity, and image fidelity of today’s state-of-the-art laser-based microscopes. The filter spectra are optimized to capture the maximum fluorescence from mCherry and other similar fluorophores while offering superb blocking of popular 593.5 nm (Double DPSS), 594 nm (HeNe), and 594.1 nm (DPSS) and 594+/-0.3 nm lasers. The dichroic offers excellent flatness for minimal focus shift and aberrations of the laser beam spot at the sample.Our improved version is certified to deliver dichroic flatness
