Apparatuses are disclosed having an ultraviolet lamp, a reflector system arranged to project light emitted from the lamp to a region 2-4 feet from a floor of a room in which the apparatus is arranged, and a mobile carriage with operational components for the apparatus. The apparatuses are configured such that the lamp is not moveable beyond vertical planes aligned with a casing of the carriage. Other apparatuses are disclosed having an ultraviolet lamp and configurations for moving the lamp relative to a structure of the apparatuses while the lamp is emitting light. Yet other apparatuses are disclosed having an ultraviolet lamp and a surrounding housing, a reflector to redirect light emitted from the lamp, an actuator for moving the reflector and the housing together relative to a structure supporting the lamp, and a rotator distinct from the actuator for rotating the reflector and housing relative to the structure.

A plasma cell for use in a laser-sustained plasma light source includes a plasma bulb configured to contain a gas suitable for generating a plasma. The plasma bulb is transparent to light from a pump laser, wherein the plasma bulb is transparent to at least a portion of a collectable spectral region of illumination emitted by the plasma. The plasma bulb of the plasma cell is configured to filter short wavelength radiation, such as VUV radiation, emitted by the plasma sustained within the bulb in order to keep the short wavelength radiation from impinging on the interior surface of the bulb.

Apparatuses are disclosed which have an ultraviolet light lamp, a housing transparent to ultraviolet light surrounding the lamp and an exhaust duct extending from a gas outlet of the housing into a support structure that has an outlet disposed along its lower half portion or its bottom surface. Other embodiments of apparatuses are disclosed which have a pulsed ultraviolet light lamp and a sensor system to monitor and determine when to replace the pulsed lamp based on pulse count.
