The 65-706 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its center wavelength of 580nm, with a full width at half maximum (FWHM) of 10nm. The filter is mounted, providing a convenient and ready-to-use solution for various optical applications.
The filter's geometry includes a diameter of 25mm and a thickness of 7.5mm, making it suitable for applications that require a substantial optical path length. The filter is cut on at 575nm and cut off at 585nm, ensuring a tight passband around the desired wavelength.
The 65-706 filter features a traditional coating on both the front and back surfaces, specifically the EDM 65-646 coating. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission. The filter's shape is that of a thin lens, further expanding its potential applications.
The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its high-quality construction, precise specifications, and versatile design, the 65-706 is an excellent choice for researchers and engineers in need of a reliable bandpass interference filter.
