645FG07-50S 50x50mm RG-645 Colored Glass Long Pass Filter by Andover Corporation

The 645FG07-50S is a 50x50mm RG-645 Colored Glass Long Pass Filter, available from the Andover Corporation. This filter is part of their extensive catalog of optical elements, designed to provide a wide range of options for users in various industries.

The filter is of the 'Color Glass' subtype, which means it is made from a colored glass material. This specific filter is rectangular in shape, making it suitable for a variety of applications where a square or rectangular filter is required. The base shape is a Thin Lens, which suggests a compact design with a thickness of 3mm, providing a balance between durability and compactness.

The filter's primary function is as a Long Pass Filter, with a cut-on wavelength of 645nm. This means it allows light with wavelengths longer than 645nm to pass through while blocking or attenuating shorter wavelengths. The physical data indicates that the cut-off wavelength is 0nm, suggesting that it blocks all wavelengths of light shorter than 645nm.

The coating on both the front and back surfaces of the filter is 'and 645fg07'. This coating likely contributes to the filter's performance, possibly enhancing its long pass characteristics or providing additional protection for the glass.

The filter's geometry includes a width of 50mm and a height of 50mm, making it a square filter. This size is commonly used in various optical systems, including microscopy, spectroscopy, and imaging applications.
