67-870 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 228nm

The 67-870 is a Bandpass Filter with a circular base shape, designed and manufactured by Edmund Optics. This filter is mounted with a diameter of 50 mm and a thickness of 3.5 mm, making it suitable for various optical applications. The filter features a UVFS MAL-1965 material ID, specifically designed for use in the ultraviolet spectrum.

The 67-870 filter is designed to transmit light within a specific wavelength range, with a central wavelength (CWL) of 228nm. The cut-on wavelength is 223nm, and the cut-off wavelength is 233nm, providing a narrow bandwidth for precise optical filtering. This filter is coated with EDM 67-736 on both the front and back surfaces, enhancing its performance and durability.

The filter is shaped as a thin lens, which is beneficial for applications that require minimal optical path length distortion. The 67-870 is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. This filter is a reliable and high-performance option for applications that require precise optical filtering in the ultraviolet spectrum.
