68-337 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 228nm

The 68-337 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use at a center wavelength of 228nm, with a full width at half maximum (FWHM) of 25nm. The filter is mounted, providing a convenient and ready-to-use solution for various optical applications.

The filter's geometry includes a diameter of 25mm and a thickness of 3.5mm, making it suitable for applications that require a substantial optical path length. The cut-on wavelength is 215.5nm, and the cut-off wavelength is 240.5nm, providing a narrow band of transmission.

The 68-337 filter features a thin lens shape, which is beneficial in applications where minimal optical aberrations are required. The front and back surfaces of the filter are coated with EDM 68-336, a traditional coating that enhances the filter's performance and durability.
