The 65-652 is a Bandpass Filter, specifically designed and manufactured by Edmund Optics. This filter is circular in shape, with a diameter of 12.5 mm and a thickness of 7.5 mm, making it suitable for a wide range of optical applications. The filter is made from UVFS Mal-1965, a material known for its optical properties and durability.
The 65-652 filter is designed to operate at a central wavelength of 636 nm, with a full width at half maximum (FWHM) of 10 nm. This makes it ideal for applications that require narrowband filtering around this wavelength. The filter's cut-on wavelength is 631 nm, and the cut-off wavelength is 641 nm, further enhancing its ability to filter specific wavelengths.
The filter features a front and back coating of EDM 65-652, which is designed to enhance its performance and durability. The filter's shape is that of a Thin Lens, which allows it to be easily integrated into various optical systems.
The 65-652 filter is currently in stock and available for purchase through the Edmund Optics website. For more information, please refer to the provided weblink.
