86-968 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 775nm

The 86-968 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. This filter features a circular shape with a 50 mm diameter and a thickness of 3.5 mm, making it suitable for a wide range of applications. The filter is manufactured by Edmund Optics, a leading global manufacturer and supplier of optical components.

The 86-968 filter is designed to transmit light in the center wavelength (CWL) of 775 nm, with a full width at half maximum (FWHM) of 50 nm. This means it allows light in a very specific range around the CWL to pass through while blocking out other wavelengths. The filter's cut-on wavelength is 750 nm, and the cut-off wavelength is 800 nm, further enhancing its ability to selectively transmit light.

The filter is hard coated on both the front and back surfaces with EDM 86-944, a proprietary coating developed by Edmund Optics. This coating provides excellent environmental stability, making the filter suitable for use in various conditions. The filter's shape is defined as a Thin Lens, which is a lens with a thickness much less than its diameter, designed to minimize optical aberrations.

The 86-968 filter is currently in stock and available for purchase through the Edmund Optics website. It is cataloged under the number 86-968 and provides a valid and reliable option for those seeking a high-quality Bandpass Filter.
