780FG07-165S 165x165mm RG-780 Colored Glass Long Pass Filter by Andover Corporation

The 780FG07-165S is a rectangular long pass filter, measuring 165x165mm, designed for use in optical systems that require a specific wavelength cut-on. This filter is manufactured by Andover Corporation, a leading vendor in the optical industry, known for their high-quality and reliable products.

The filter is made of colored glass, a material identified as UVFS MAL-1965, and has a base shape of a thin lens. It is designed to pass wavelengths of 780nm and above, making it ideal for applications where longer wavelengths need to be isolated or emphasized. The filter's geometry includes a thickness of 3mm, providing durability and stability in its placement within an optical system.

The physical data of the filter indicates a cut-on wavelength of 780nm and a cut-off wavelength of 0nm. This means that all wavelengths at and above 780nm will pass through the filter, while wavelengths below this will be blocked. The filter's coating, applied to both the front and back surfaces, is identified as 'and 780fg07'. This coating likely contributes to the filter's performance and durability.
