67-823 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=6.9 mm 330nm

The 67-823 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in applications where precise wavelength selection and narrow bandwidth are critical. The filter features a center wavelength (CWL) of 330nm, with a full width at half maximum (FWHM) of 10nm, making it ideal for use in ultraviolet (UV) applications.

The filter is constructed with a thickness of 6.9mm, providing excellent durability and stability. It is cut on at 325nm and cut off at 335nm, ensuring sharp wavelength discrimination. The filter is coated on both the front and back surfaces with EDM 67-756, a traditional coating that enhances its performance and longevity.

The 67-823 filter is designed in a thin lens shape, which allows for easy integration into optical systems. It is mounted, providing convenience and ease of use. The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
