46-421 50.8 x 50.8 mm SCHOTT N-WG320 Longpass Color Glass Filter 320nm

The 46-421 50.8 x 50.8 mm SCHOTT N-WG320 Longpass Color Glass Filter is a high-quality optical component designed for use in a wide range of applications. Sourced from the renowned optical vendor Edmund Optics, this filter is a Rectangular-shaped Color Glass type, boasting a robust and reliable UVFS MAL-1965 material ID.

The filter's primary function is to allow light transmission at wavelengths equal to or greater than 320nm, while blocking light at wavelengths below this cut-on value. This makes it ideal for use in applications where longpass filtering is required, such as in fluorescence microscopy, spectroscopy, and other optical systems.

The filter's physical dimensions are 50.8mm in width and 50.8mm in height, with a thickness of 3mm. This size makes it suitable for use in a variety of optical setups. The cut-on wavelength of 320nm is physically applied to the filter, ensuring precise and consistent longpass filtering.

The filter's coating is a crucial aspect of its design. Both the front and back surfaces of the filter are coated with EDM 46-419, a coating specifically designed to enhance the filter's performance and durability. This coating helps to ensure optimal light transmission and reduces the risk of surface damage.

The filter's shape is classified as a Thin Lens, indicating its suitability for use in optical systems where thin, lightweight elements are required. This shape also aids in minimizing optical aberrations, further enhancing the filter's performance.
