Dichroic Long Pass Filter for Flow Cytometry applications   

FLD 642 DLP   

Designed to isolate one band of wavelengths from another by reflection or transmission, these filters are used to separate the excitation source wavelength from the emission wavelengths in flow cytometry and spectroscopy.

The high blocking of these edge filters improves spectral noise reduction by eliminating the need for additional filtering, and the hard dielectric coatings do not require cover glasses for durability thus greatly improving transmission levels compared to traditional filters.
