67-912 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 770nm
The 67-912 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its 50 mm diameter and 5.9 mm thickness, making it suitable for a wide range of applications. The filter's primary function is to allow light in a specific wavelength range to pass through while blocking other wavelengths.
The 67-912 filter is designed to operate at a central wavelength (CWL) of 770 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows light between 765 nm and 775 nm to pass through, making it ideal for applications that require narrow-band filtering around this wavelength.
The filter's coating is another crucial aspect. Both the front and back surfaces are coated with EDM 67-778, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing reflection and increasing transmission, ensuring optimal light passage.
The filter's geometry is that of a thin lens, which adds to its versatility. It can be used in various optical systems without causing significant disruptions or aberrations. The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
