15-459 25.4 mm Dia. Dielectric Coated Colored Glass Replacement Longpass Filter 665nm
The 15-459 is a 25.4 mm diameter dielectric coated colored glass replacement longpass filter with a cut-on wavelength of 665nm, available from Edmund Optics. This filter is designed for use in optical systems where longpass filtering is required, with a high transmission rate for wavelengths above 665nm and a blocking effect for shorter wavelengths.
The filter is made from UVFS Mal-1965 material, a type of colored glass specifically designed for optical applications. It has a circular base shape and a thin lens design, with a thickness of 1.1mm, making it suitable for use in compact optical systems. The filter is coated on both the front and back surfaces with EDM 15-449, a dielectric coating that enhances its longpass filtering properties.
The 15-459 filter is currently in stock and available for purchase through the Edmund Optics website. It is part of a wide range of optical filters offered by the vendor, providing users with a diverse selection of components to choose from for their optical systems.
