67-893 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.4 mm 355nm

The 67-893 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 50 mm and a thickness of 5.4 mm, making it suitable for a wide range of optical applications.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking light outside this range. In this case, the filter is designed to pass light with a central wavelength (CWL) of 355 nm, with a full width at half maximum (FWHM) of 10 nm. This makes it ideal for applications that require precise wavelength selection in the ultraviolet range.

The 67-893 filter features a cut-on wavelength of 350 nm and a cut-off wavelength of 360 nm. This means that it begins to transmit light at 350 nm and stops transmitting at 360 nm, effectively filtering out any wavelengths outside this range.

The filter is coated with EDM 67-759 on both the front and back surfaces. This coating enhances the filter's performance and durability, providing improved transmission and resistance to environmental factors.

The filter's shape is described as a thin lens, which refers to its optical design and construction. This shape is often used in optical systems where a thin, lightweight element is required.
