84-897 25.4 mm Dia. SCHOTT UG5 (UV) Black Colored Glass Bandpass Filter 318nm

The 84-897 is a 25.4 mm diameter circular filter from Edmund Optics, designed for use in UV applications with a center wavelength of 318nm. This filter is made from SCHOTT UG5 (UV) glass, a high-performance optical material renowned for its excellent transmission and low autofluorescence in the UV range.

The filter features a black colored glass bandpass design, which provides high transmission at the desired wavelength while effectively blocking unwanted light in the spectral regions adjacent to the passband. This makes it ideal for applications that require narrowband UV transmission, such as fluorescence microscopy, UV-VIS spectroscopy, and optical sensing.

The 84-897 filter has a thickness of 3mm and is coated on both sides with EDM 84-897, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving environmental stability. The filter is designed in a thin lens shape, ensuring easy integration into optical systems.

According to the vendor's information, the 84-897 filter is currently in stock and can be purchased directly from the Edmund Optics website. The filter's catalog number is 84-897, and more information, including technical specifications and pricing, can be found at https://www.edmundoptics.com/p/ug-5-uv-254mm-dia-colored-glass-bandpass-filter-/27892/.
