320FG01-50 50mm Dia. WG-320 Colored Glass Long Pass Filter by Andover Corporation

The 320FG01-50 is a 50mm diameter Colored Glass Long Pass Filter, designed and manufactured by the reputable Andover Corporation. This filter, with the catalog number 320FG01-50, is a crucial component in various optical systems, particularly those requiring long-wave pass functionality.

The filter's primary role is to allow light of longer wavelengths to pass through while blocking or attenuating shorter wavelengths. In this case, the cut-on wavelength is 320 nanometers, indicating that it begins to transmit light at this point of the spectrum. The cut-off wavelength, however, is 0 nanometers, suggesting that it does not block any wavelengths of light from transmission.

The 320FG01-50 filter is made from UVFS Mal-1965, a specific material known for its optical properties. It features a Thin Lens shape, which is beneficial in applications where space is a constraint or a flat surface is required. The filter's geometry includes a diameter of 50 millimeters and a thickness of 3 millimeters, making it suitable for various optical setups.

The filter's coating is applied to both the front and back surfaces, specifically the AND 320FG01 coating. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation in its intended application.
