Fluorescence Filter Sets

Materion Balzers Optics fluorescence filter sets include excitation and emission filters (bandpass, shortpass or longpass) as well as a dichroic beamsplitter. Cut-on and cut-off wavelengths of the filters are optimized for the excitation light source and for the fluorescent dye. The filter performance is realized by all-dielectric hard coatings deposited onto a single substrate. Because absorbing glasses and filter mounts are not needed, there is a high flexibility for the filter dimensions in compact optical set-ups.
