86-638 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 852nm
The 86-638 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its 50 mm diameter and 7.5 mm thickness, making it suitable for a wide range of optical applications.
The filter's primary function is to allow light in a specific wavelength range to pass through while blocking other wavelengths. In this case, the central wavelength (CWL) is 852 nm, with a full width at half maximum (FWHM) of 10 nm. The cut-on wavelength is 847 nm, and the cut-off wavelength is 857 nm, further enhancing its selectivity.
The 86-638 filter features a thin lens shape and is made from UVFS Mal-1965 material. It is coated on both the front and back with EDM 65-666, ensuring optimal performance and durability.
This filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its high-quality construction and precise specifications, the 86-638 is an excellent choice for those seeking a reliable and effective bandpass interference filter.
