Fluorescence Filter

Fluorescence filters provide excellent solutions in the field of in vivo imaging and fluorescence-based measurement such as cytometry, DNA sequencing, and fluorescence microscopy.

Most fluorescence instruments are based on optical filters. The system has three basic filters which are "excitation filter” , "dichroic" and "emission filter” .
