Longpass and Dichroic Edge Filters are used to transmit long wavelengths while rejecting short wavelengths in a wide range of applications such as beam separation, microscopy, or spectroscopy. Longpass and Dichroic Edge Filters are designed to transmit all wavelengths beyond a particular wavelength on the spectrum. Longpass and Dichroic Edge Filters use a range of substrates or coatings to determine the transmission or rejection efficiencies. Dichroic Filters possess a very narrow transmission width. Longpass and Dichroic Edge Filters are available in a wide range of wavelengths.
