65-724 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 800nm
The 65-724 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its 25 mm diameter and 7.5 mm thickness, making it a substantial yet manageable component for various 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 800nm, with a full width at half maximum (FWHM) of 10nm. The cut-on wavelength is 795nm, and the cut-off wavelength is 805nm, indicating a narrow and precise band of light transmission.
The filter's coating is a critical aspect of its performance. Both the front and back surfaces are coated with EDM 65-664, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance, ensuring optimal light transmission and blocking unwanted wavelengths.
The filter's shape is that of a thin lens, suggesting its potential use in lens systems. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
