• Longpass Region: 715 nm - 1800 nm
• Ø25 mm Round
• Fabricated from 2 mm Thick RG715 Schott Glass

This longpass colored glass filter is manufactured from RG715 Schott glass and is intended for use in a wide variety of applications. This Ø25 mm round filter will fit into our manual or motorized filter wheels; alternatively, it can be mounted in a lens tube.

Colored glass filters are designed for use with broadband sources. When used with narrowband lasers, fluorescence may occur with some of the substrates at certain wavelengths. For narrowband sources, we recommend our dielectric edgepass filters.
