67-749 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 300nm

The 67-749 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 primary material, ensuring durability and high-quality performance. It is designed to operate at a central wavelength of 300nm, with a full width at half maximum (FWHM) of 10nm. This specificity in wavelength makes it ideal for applications that require precise filtering in the ultraviolet spectrum.

The 67-749 features a cut-on wavelength of 295nm and a cut-off wavelength of 305nm, providing a narrow and precise bandpass. The filter's coating, applied on both the front and back surfaces, is specifically designed to enhance its performance and durability. This coating, identified as EDM 67-749, is a proprietary coating developed by Edmund Optics.

The filter's geometry and shape are designed to function as a thin lens, allowing for easy integration into various optical systems.
