Shortpass Edge Filters

Shortpass Filters are used to isolate short wavelengths while rejecting long wavelengths for a wide range of applications such as beam separation, microscopy, or spectroscopy. Shortpass Filters reflect all wavelengths beyond a particular wavelength. Dichroic Filters are also available, which possess very narrow transmission widths. Shortpass Filters are offered in a wide range of different wavelengths, as well as a range of substrates or coatings to determine the transmission/reflection efficiency.
