67-811 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 265nm

The 67-811 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use at a central wavelength (CWL) of 265 nanometers, with a full width at half maximum (FWHM) of 10 nanometers.

The filter is constructed with a base shape of a circle, and it features a thickness of 3.5 millimeters. The material used in its construction is UVFS Mal-1965, a material well-suited for applications in the ultraviolet spectrum.

The 67-811 filter is designed with precise cut-on and cut-off wavelengths of 260 nanometers and 270 nanometers, respectively. This ensures that only light within the specified wavelength range is transmitted, making it ideal for applications requiring narrow-band filtering.

The filter is coated with EDM 67-744 on both the front and back surfaces. This coating enhances the filter's performance and durability, ensuring reliable operation in a variety of environments.

The filter's shape is that of a thin lens, making it suitable for use in optical systems where minimal thickness and weight are desirable. The filter is currently in stock and available for purchase through the Edmund Optics website.
