The 84-900 is a 50.8 x 50.8 mm SCHOTT UG11 (UV) Black Colored Glass Bandpass Filter, specifically designed for use at a wavelength of 325nm. This filter is sourced from the reputable optical components vendor, Edmund Optics.
The filter is a Color Glass type, which is known for its ability to selectively transmit light within a specific range of wavelengths while blocking other wavelengths. This particular model is designed for UV applications, making it suitable for use in systems where UV light transmission is required.
The filter has a rectangular base shape, with a width and height of 50.8mm each. It has a thickness of 3mm, providing sufficient structural integrity for most applications. The filter's coating, denoted as 'edm 84-899' on both the front and back, contributes to its functionality, although the specifics of this coating are not detailed in the provided data.
The physical data of the filter indicates a central wavelength (CWL) of 325nm, which is the wavelength at which the filter is most efficient. The filter's geometry and physical data make it a suitable component for a variety of optical systems, particularly those involving UV light.
