Abstract

Official abstract text for this publication.

The detector in accordance with the present invention includes: a light emitter; a light receiver; and a light guiding member which includes a detection space for determining a state of a predetermined gas and is configured to guide light emitted from the light emitter to the at least one light receiver through the detection space. An internal surface of the detection space of the light guiding member includes a reflective surface causing reflection of light emitted from the light emitter. The reflective surface is a concave ellipsoidal surface having a long axis defined by a straight line determined by the light emitter and the light receiver. The reflective surface has a first focal point at a position of the light emitter and a second focal point on an opposite side of the light receiver from the first focal point.
