Band-pass optical filter

long-passshort-wave passdichroic

Achieve low-noise fluorescence detection in life sciences instrumentation by efficiently separating the fluorescence from any scattered excitation light. Optimized for your specific OEM application and fluorophore, Coherent will work with your team to design a perfectly matched filter set. We use multiple types of thin film coating technologies to create bandpass, long pass, short pass, dichroic, and other filters. Benefit from hard-coated excitation and emission filters that provide precise wavelength control, industry-leading transmission, very steep edges, and superior blocking.
