67-917 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 820nm

The 67-917 is a Bandpass Filter, specifically designed with a circular base shape and mounted diameter of 50 mm. This filter is sourced from the reputable vendor, Edmund Optics, and boasts a Material ID of UVFS MAL-1965. The filter's primary function is to allow light transmission within a specific range of wavelengths, thereby reducing unwanted noise and enhancing signal clarity.

The 67-917 is designed to operate at a central wavelength (CWL) of 820 nm, with a full width at half maximum (FWHM) of 10 nm. This precise wavelength range is achieved through the use of advanced coating technology on both the front and back surfaces, specifically the EDM 67-783 coating. This coating ensures high transmission efficiency and excellent optical quality.

The filter's physical data includes cut-on and cut-off wavelengths of 815 nm and 825 nm, respectively. This means that the filter begins to transmit light at 815 nm and stops transmitting at 825 nm, effectively isolating the desired wavelength range.

The 67-917 has a thickness of 5.9 mm and features a Thin Lens shape. This filter is currently in stock and available for immediate purchase through the provided weblink. With its high-quality construction, precise wavelength specifications, and reliable performance, the 67-917 is an excellent choice for a wide range of optical applications.
