65-711 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 632nm

The 65-711 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 632 nm, with a full width at half maximum (FWHM) of 10 nm. The filter is mounted, providing a convenient and ready-to-use solution for various optical applications.

The filter's geometry includes a diameter of 25 mm and a thickness of 7.5 mm, making it suitable for applications where a substantial optical path difference is required. The filter is cut on at 627 nm and cut off at 637 nm, ensuring a narrow bandwidth around the central wavelength of 632 nm.

The 65-711 filter features a traditional coating on both the front and back surfaces, identified as EDM 65-651. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission in the desired wavelength range.

The filter's shape is defined as a thin lens, suggesting that it may have some degree of lens-like properties, such as a curved surface or a specific refractive index. However, the exact lens parameters are not provided in the item data.
