(JA) 光度計
Abstract:
(EN) A photometer (100) provided with a light source (1) and an optical element (30) and detector (5) disposed on the optical path P of the light emitted from the light source (1), wherein the photometer is provided with: a light reduction filter (24a), which is disposed on the optical path P between the light source (1) and the optical element (30), for blocking a portion of the light emitted from the light source (1) and allowing the remaining light to pass; and a state monitoring unit (83) for monitoring whether the light source (1) and optical element (30) are in a stable state by monitoring the light that has passed through the light reduction filter (24a) at a stage after the optical element (30).
(FR) La présente invention concerne un photomètre (100) pourvu d’une source lumineuse (1) et d’un élément optique (30) et un détecteur (5) disposé sur le trajet optique P de la lumière émise par la source de lumière (1), le photomètre étant pourvu de : un filtre de réduction de lumière (24a), qui est disposé sur le trajet optique P entre la source de lumière (1) et l’élément optique (30), pour bloquer une partie de la lumière émise par la source de lumière (1) et laisser passer la lumière restante ; et une unité de surveillance d’état (83) pour surveiller si la source de lumière (1) et l’élément optique (30) sont dans un état stable par surveillance de la lumière qui a traversé le filtre de réduction de lumière (24a) à un stade après l’élément optique (30).
(JA) 光源(1)と、光源(1)から出射される光の光路P上に配置された光学素子(30)および検出器(5)とを備える光度計(100)において、光路P上であって、光源(1)と光学素子(30)との間に配置され、光源(1)から出射される光の一部を遮蔽しつつ残りを透過させる減光フィルタ(24a)と、減光フィルタ(24a)を透過した光を光学素子(30)よりも後段側でモニタリングすることにより、光源(1)および光学素子(30)が安定状態にあるか否かを監視する状態監視部(83)と、を備える。
