15-455 25.4 mm Dia. Dielectric Coated Colored Glass Replacement Longpass Filter 420nm

The 15-455 is a 25.4 mm diameter colored glass replacement longpass filter, specifically designed for applications requiring a cut-on wavelength of 420nm. Sourced from the renowned optical vendor Edmund Optics, this filter is part of their extensive catalog, boasting high-quality components for a wide range of applications.

This filter is a type of Color Glass filter, featuring a circular geometry with a diameter of 25.4mm and a thickness of 1.1mm. The filter's primary function is to allow the transmission of longer wavelengths while blocking or reducing the transmission of shorter wavelengths. This is achieved through the dielectric coating on both the front and back surfaces, specifically the EDM 15-445 coating.

The physical data of the 15-455 filter indicates a cut-on wavelength of 420nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength, on the other hand, is 0, indicating that it allows all wavelengths longer than 420nm to pass through.

The filter's shape is classified as a Thin Lens, suggesting it may have some light bending properties. However, this is not its primary function, and the lens properties should be verified with the vendor for specific applications.

The 15-455 filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status. For more detailed information, users are encouraged to visit the provided weblink.
