The 64-510 25.4 mm Dia. SCHOTT N-WG280 Longpass Color Glass Filter is a specialized optical component designed for applications that require longpass filtering at a wavelength of 285nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.
The filter is a circular component with a diameter of 25.4mm and a thickness of 3mm, making it suitable for a wide range of optical systems. It is made from SCHOTT N-WG280 glass, a material known for its excellent optical properties and durability. The filter is coated on both the front and back sides with the EDM 64-509 coating, which enhances its longpass filtering capabilities.
The physical data of the filter indicates that it is cut on at 285nm, meaning that it begins to transmit light at this wavelength. The cut off value is 0, indicating that it continues to transmit light at all longer wavelengths. This makes it ideal for applications that require the blocking of shorter wavelengths while allowing the passage of longer wavelengths.
The filter is shaped as a thin lens, which is a type of lens with a very small focal length compared to its diameter. This makes it suitable for use in compact optical systems where space is at a premium.
