67-748 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 297nm

The 67-748 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its circular shape, with a diameter of 12.5 mm and a thickness of 3.5 mm, making it suitable for a wide range of optical applications.

The filter is constructed using UVFS MAL-1965 as its base material, a choice that enhances its performance in specific wavelength ranges. The 67-748 is designed to operate at a central wavelength of 297nm, with a full width at half maximum (FWHM) of 10nm. This makes it ideal for applications that require narrowband filtering in the ultraviolet spectrum.

The 67-748 features a cut-on wavelength of 292nm and a cut-off wavelength of 302nm. These values are crucial in determining the filter's ability to block unwanted wavelengths, thereby enhancing the signal-to-noise ratio in the desired wavelength range.

The filter is coated on both the front and back surfaces with EDm 67-748, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing reflection and increasing transmission in the desired wavelength range.

The 67-748 is designed in a thin lens shape, which not only enhances its optical performance but also makes it compatible with various optical systems. According to the vendor's information, this filter is currently in stock and available for immediate shipping.
