84-898 50.8 x 50.8 mm SCHOTT UG5 (UV) Black Colored Glass Bandpass Filter 318nm

The 84-898 is a 50.8 x 50.8 mm SCHOTT UG5 (UV) Black Colored Glass Bandpass Filter, designed to transmit light within a specific range of wavelengths around 318nm. This filter is sourced from Edmund Optics, a leading provider of optical components.

The filter is a Color Glass type, which means it's made from a single piece of colored glass. It's rectangular in shape, with a width and height of 50.8mm each, and a thickness of 3mm. The UG5 (UV) designation indicates that this filter is specifically designed for use in the ultraviolet region of the spectrum.

The filter's coating is a crucial part of its design. Both the front and back surfaces are coated with EDM 84-897, a coating that enhances the filter's performance and durability. The coating helps to ensure that the filter transmits light efficiently within its specified wavelength range, while also providing protection against environmental factors.

The filter's geometry is defined as a Thin Lens, which suggests that it's designed to be used in optical systems where minimal thickness and weight are important. The CWL (Central Wavelength) of the filter is 318nm, which is the wavelength at which the filter's transmission is at its maximum.
