Fluorescence imaging dichroic filter

Dichroic mirror, beam splitter, combiner and dichroic filter provide different beam splitting ratios for incident light in different bands. Dichroic mirrors can be used to combine or separate laser beams of different colors.


The fluorescent imaging dichroic mirror / dichroic filter provided by Borisun Optics is specially designed for fluorescent imaging applications. Our dichroic filter is designed to separate different wavelengths. When the angle of the incident light relative to the normal of the filter is 45 degrees, the excitation light and its back reflected light are reflected, and the fluorescence signal with longer wavelength is transmitted. They are manufactured in industry standard sizes, so they are compatible with filter cubes from all major manufacturers.
