46-425 12.5 mm Dia. SCHOTT GG420 Yellow Longpass Color Glass Filter 420nm
The 46-425 is a 12.5 mm diameter Color Glass Filter from SCHOTT, available through Edmund Optics. This filter, designed for use in optical systems, features a longpass cut-on wavelength of 420nm, making it ideal for applications that require the transmission of longer wavelengths while blocking shorter ones.
The filter is made from UVFS Mal-1965 material, a Schott glass known for its excellent optical properties and durability. It boasts a circular base shape and a thin lens geometry, ensuring easy integration into various optical systems. The filter's diameter measures 12.5mm, while its thickness is 3mm, providing a robust yet compact component.
The 46-425 filter is coated on both the front and back surfaces with EDM 46-425, a coating that enhances its performance and longevity. This coating helps to ensure the filter's cut-on wavelength remains consistent, providing reliable performance in your optical system.
The filter's physical data indicates a cut-on wavelength of 420nm and a cut-off wavelength of 0nm. This specificity in wavelength transmission makes the 46-425 a versatile tool in a wide range of optical applications.
