86-639 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 940nm
The 86-639 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter features a circular shape with a 50 mm diameter and a thickness of 7.5 mm, making it suitable for a wide range of optical applications.
The filter is designed to operate at a central wavelength (CWL) of 940 nm, with a full width at half maximum (FWHM) of 10 nm. The cut-on wavelength is 935 nm, and the cut-off wavelength is 945 nm, providing a narrow bandwidth that can help to reduce unwanted noise and improve signal clarity in your optical system.
The 86-639 filter is coated with EDM 65-670 on both the front and back surfaces. This coating helps to enhance the filter's performance by reducing reflection and increasing transmission. The filter is mounted, making it easy to integrate into your optical system.
The filter is currently in stock and available for purchase through the Edmund Optics website. For more information, please refer to the provided weblink.
