The 280FG01-25 is a 25mm diameter Colored Glass Long Pass Filter, designed and manufactured by the reputable Andover Corporation. This filter, with the catalog number 280FG01-25, is a crucial component in various optical systems, particularly those requiring specific wavelength management.

The filter is of the Long Pass type, meaning it allows wavelengths longer than a specified value to pass through while blocking shorter wavelengths. In this case, the cut-on wavelength is 280 nanometers, making it ideal for applications where longer wavelengths need to be isolated or emphasized. The cut-off wavelength is 0 nanometers, indicating that no wavelengths shorter than the cut-on are allowed to pass.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It has a base shape of a circle, a common choice for its ease of integration into various optical setups. The filter's geometry includes a diameter of 25 millimeters and a thickness of 3 millimeters, providing a robust and compact design.

The coating on both the front and back surfaces of the filter is 'and 280fg01'. This coating is crucial as it enhances the filter's performance and durability. The filter's shape is a Thin Lens, further optimizing its performance in optical systems.
