67-822 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=6.9 mm 326nm

The 67-822 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its circular shape and thin lens design, making it suitable for a wide range of applications. The filter has a diameter of 25 mm and a thickness of 6.9 mm, providing a compact yet robust structure.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking light outside this range. The central wavelength (CWL) of this filter is 326 nm, with a full width at half maximum (FWHM) of 10 nm. This makes it ideal for applications that require precise filtering in the ultraviolet range.

The filter's cut-on wavelength is 321 nm, and the cut-off wavelength is 331 nm. This means that it begins to transmit light at 321 nm and stops transmitting at 331 nm, effectively filtering out unwanted wavelengths.

The filter is coated with EDM 67-755 on both the front and back surfaces. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation.

The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its robust design, precise filtering capabilities, and high-quality coating, the 67-822 is an excellent choice for various applications in the ultraviolet range.
