Abstract
A Far UV C excimer bulb assembly including an excimer bulb, and at least two filters. The excimer bulb emits a path of light in at least two wavelengths. The at least two filters remove all wavelengths of light that are hazardous to human tissue. The at least two filters may each be placed perpendicular to the path of the light generated by the excimer bulb. The at least two filters may be a single, curved or cylindrical filter. The assembly may further include a mirror which may also be curved.
