Abstract
An ultraviolet ray emitter includes an inner tube, an outer tube arranged around the inner tube, the outer tube defining between the outer tube and the inner tube, a discharge space where discharge gas is sealed, a pair of electrodes that causes discharge in the discharge space, and an auxiliary light source that assists excitation of discharge gas by emitting light to discharge gas from the outside of the outer tube. The outer tube is less likely to allow passage therethrough of ultraviolet light generated by excitation of discharge gas than the inner tube but allows passage therethrough of light having a wavelength emitted from the auxiliary light source.
Claims12
An inspection apparatus that inspects sample water, the inspection apparatus comprising:
- an ultraviolet ray emitter;
- and
- a detector that detects a subject component contained in the sample water, wherein
- the ultraviolet ray emitter includes:
- an inner tube,
- an outer tube arranged around the inner tube, the outer tube defining between the outer tube and the inner tube, a discharge space where discharge gas is sealed,
- a pair of electrodes that causes discharge in the discharge space, and
- an auxiliary light source that assists excitation of the discharge gas by emitting light to the discharge space from outside of the outer tube,
- the auxiliary light source emits light longer in wavelength than ultraviolet light generated by excitation of the discharge gas, wherein
- the outer tube is composed of a material that is configured to pass less of the ultraviolet light than a material of the inner tube, but allows passage of light having the wavelength emitted from the auxiliary light source.
