Fluorescent filter sets are essential components in fluorescence microscopy and imaging, designed to optimize the detection of fluorescent signals while minimizing background noise. Here’s an overview of the key components and considerations:

Components of Fluorescent Filter Sets

1. Excitation Filter:
   • This filter only allows light of a specific wavelength (or range of wavelengths) to pass through, which excites the fluorescent dye or marker used in the specimen.
2. Dichroic Mirror:
   • The dichroic mirror reflects the excitation light towards the sample while allowing the emitted fluorescent light (of longer wavelengths) to pass through to the detector. The angle and coating of the mirror are critical for effective separation of the excitation and emission light.
3. Emission Filter ... Read more »
