67-925 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 900nm

The 67-925 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 67-925 filter is designed to operate at a central wavelength (CWL) of 900 nm, with a full width at half maximum (FWHM) of 40 nm. This means it allows light with a wavelength close to 900 nm to pass through while blocking light with wavelengths further from this value. The filter's cut-on wavelength is 880 nm, and the cut-off wavelength is 920 nm, further illustrating its selective properties.

The filter's coating plays a crucial role in its performance. Both the front and back surfaces of the filter are coated with EDM 67-791, a specific coating type that enhances the filter's efficiency and durability. The filter's shape is that of a thin lens, which contributes to its compact design and ease of integration into various optical systems.
