This 7-filter “Pinkel” penta-band set is designed for imaging of a sample that is simultaneously labeled with DAPI, FITC, TRITC, Cy5, and Cy7 (or other key fluorophores – see complete list above). This state-of-the-art set represents a break-through in penta-band performance, and has been optimized for popular LED-based light sources. This set has been designed to deliver significant fluorescence signal improvements for LED-based light sources compared with traditional sets designed for standard broadband light sources such as mercury or xenon arc lamps. The complete set is comprised of a penta-band beamsplitter and a penta-band emitter (these can be offered assembled in a microscope cube), plus five “no burn-out” single-band exciters that are intended to be mounted in the LED based light source, or in an exciter filter wheel or slider.
