How does a fluorescent filter work?
Fluorescence filters are key components in microscopy, used to selectively transmit light for exciting and detecting fluorescence. They include excitation, emission, and barrier filters. Excitation filters stimulate fluorescence, emission filters capture it, and barrier filters block excitation light. Specific filters, like DAPI, FITC, GFP, Cy5, Texas Red, Cy3, mCherry, and Rhodamine, are tailored for different fluorophores, aiding precise biological imaging.
