光プローブ。[Claims for Utility Model Registration] (1) A light source, an optical system that converts light from the light source into cylindrical parallel rays, and an optical system in which the cylindrical parallel rays are irradiated onto the outer surface of a peripheral wall in the direction of the parallel rays. a conical first ray disposed coaxially with the central axis of the parallel rays so that the parallel rays are reflected in an all-outward direction at a substantially right angle;
a reflecting mirror, and a funnel-shaped mirror arranged to surround the first reflecting mirror, and reflecting the light beam reflected by the first reflecting mirror on the inner surface of the side wall to form an annular parallel light beam. a second reflecting mirror, and the annular parallel light beam formed by being reflected by the second reflecting mirror is reflected on the inner surface of the side wall to illuminate the surface of the object to be measured disposed inside the side wall. 3rd truncated cone
An annular irradiation type photometric probe with a built-in light source lamp, characterized by having a reflecting mirror. (2) The optical system includes an ellipsoidal reflector having a first focal point closer to the reflective surface and a second focal point farther from the reflective surface than the first focal point; a concave lens disposed between the concave lens and the second focal point, the position of one focal point being coincident with the position of the second focal point;
2. The annular irradiation type photometric probe with a built-in light source lamp according to claim 1, wherein the probe is disposed at a focal point of the probe.
