65-651 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 632nm

The 65-651 is a Bandpass Filter, a type of optical filter that allows only a specific range of wavelengths to pass through while blocking others. This particular filter is designed to work with a central wavelength of 632nm, making it suitable for applications that require this specific wavelength.

The filter has a diameter of 12.5mm and a thickness of 7.5mm, providing a substantial platform for integration into various optical systems. It features a circular base shape, a common form factor for many optical components due to its ease of alignment and integration.

The material ID for this filter is UVFS MAL-1965, a detail that may be crucial for those who need to match the filter's material properties with other components in their system. The physical data of the filter includes a cut-on wavelength of 627nm and a cut-off wavelength of 637nm, providing a narrow bandwidth for precise wavelength selection.

The filter's coating is another critical aspect. Both the front and back surfaces of the filter are coated with EDM 65-651, a coating that likely contributes to the filter's performance and durability. The filter's shape is described as a Thin Lens, suggesting that it may have some light-bending properties, although this is not explicitly stated in the provided data.

The vendor for this filter is Edmund Optics, a well-known and respected name in the optical industry. The item's web link is provided, leading to a page where users can find more information, including current availability and pricing.
