BrightLine filters have blocking far exceeding OD 6 as needed to ensure a black background, even when using modern low-noise CCD cameras. The blocking is optimized for microscopy applications using our exclusive SpecMaker™ fluorescence filter design.
BrightLine filters are available to fit Leica, Nikon, Olympus, Zeiss, and Aperio microscopes.
