86-960 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 975nm

The 86-960 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow passband. This filter features a circular shape with a diameter of 25 mm and a thickness of 3.5 mm, making it compatible with a wide range of optical components. The filter is manufactured by Edmund Optics, a leading vendor in the field of optical elements.

The filter's primary function is to transmit light within a specific wavelength range while blocking light outside this range. The 86-960 is designed to transmit light at a central wavelength (CWL) of 975 nm, with a full width at half maximum (FWHM) of 50 nm. This means it allows light between 950 nm and 1000 nm to pass through, making it ideal for applications that require a tight wavelength control.

The filter's coating plays a crucial role in its performance. Both the front and back surfaces of the filter are coated with EDM 86-948, a hard coating that enhances the filter's durability and resistance to environmental factors. This coating also helps to reduce surface reflections, improving the overall efficiency of the optical system.

The 86-960 is available for purchase through the Edmund Optics website, where it is listed as being in stock. The website also provides detailed product information, including technical specifications and application examples, to assist users in their selection process.
