1. A Far UV C excimer bulb assembly, comprising;
an excimer bulb which generates radiation in a plurality of wavelengths substantially comprising Far UV C;
a curved filter external to and separated from said excimer bulb, said curved filter including an arc;
said curved filter being hafnium based;
said 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;
said excimer bulb positioned at least partially and centered within said arc so that a majority of said Far-UV C wavelengths of radiation pass perpendicularly through said curved filter.
