67-816 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 300nm

The 67-816 is a 25 mm diameter mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its center wavelength of 300 nm and a full width at half maximum (FWHM) of 10 nm. The filter's primary function is to transmit light within a specific wavelength range while blocking other wavelengths, making it ideal for applications that require narrowband spectral filtering.

The filter's geometry includes a diameter of 25 mm and a thickness of 3.5 mm, providing a robust and stable platform for optical systems. The cut-on wavelength is 295 nm, and the cut-off wavelength is 305 nm, further enhancing its spectral filtering capabilities.

The 67-816 filter features a thin lens shape, which is beneficial for applications that require minimal optical path length distortion. The front and back surfaces of the filter are coated with EDM 67-749, a proprietary coating developed by Edmund Optics, which enhances the filter's performance and durability.
