The 46-426 is a 25.4 mm diameter circular filter from Edmund Optics, designed for longpass applications with a cut-on wavelength of 420nm. This filter is made from SCHOTT GG420, a high-quality color glass material with the catalog number UVFS Mal-1965. The filter's primary function is to transmit light with wavelengths above 420nm while blocking or attenuating wavelengths below this value.
The filter has a thickness of 3mm, which contributes to its durability and resistance to mechanical stress. It features a thin lens shape, making it suitable for a wide range of optical systems. The front and back surfaces of the filter are coated with EDM 46-425, a coating that enhances the filter's performance and durability.
The 46-426 filter is currently in stock and available for immediate purchase from the Edmund Optics website. It is a versatile and reliable component for various optical applications, particularly where longpass filtering is required.
