Abstract
An optical filter including at least one substrate and first and second thin-film interference filters disposed directly on the substrate. The interference filters include a plurality of hard coating thin film layers of alternating high and low index of refraction. A fluorescence spectroscopy system and method of selecting a band of wavelengths from light in a fluorescence spectroscopy system are also provided.
