Abstract
A Far UV C excimer bulb assembly including an excimer bulb, and a curved filter external to and separated from the excimer bulb. The curved filter being hafnium based and including an arc. The excimer bulb emits radiation in a plurality of wavelengths substantially comprising Far UV C. The curved filter having a cut-off wavelength of 234 nm and adapted to block substantially all wavelengths of UV C radiation longer than 234 nm. The excimer bulb is positioned at least partially and centered within the arc so that the majority of the Far UV C wavelengths of radiation pass perpendicularly through the curved filter. The assembly may further include a mirror which may also be curved, and plated onto the exterior surface of the excimer bulb.
