Description
Longpass filters are designed to transmit wavelengths higher than the cut on point and reflect all lower wavelengths. These dichroic longpass filters consist of thin-film dielectric coatings on glass with sharp transitions between the transmitted and reflected bands. Having negligible absorption they are suitable for high powers and do not show the strong fluorescence of certain glass filters.
Our dichroic longpass filters are available in a range of wavelengths and are supplied in standard 12.5mm and 25mm diameter or 50mm square types. We are happy to cut and edge filters for non standard sizes to suit your application.
