Product Description

 1. Brief Description:

Fluorescence microscopy filters are the essential components for fluorescence microscopy. Most of the fluorescence microscopy filters are consists of three kinds filters: exciter, emitter and dichroic filter or mirror to work properly. For the reason of different application, some system may not need them all. One exciter, one emitter placed with a special angle of incidence and no dichroic mirror needed is the most common. 


2. Application: fluorescence microscopy



3. Advantage of Standard Fuorescence filter Set for Microscopy:


(1) DAPI, FITC, Texas Red, TRITC and other more than 15 fluorophore.

(2) Standard B G UV V longpass filter set for microscope.

(3) Sing substrate 1.0mm and multi substrate for optioin.

(4) High contrast(Bright subject and dark background).
