Title (EN) OPTICAL DEVICE FOR MEASUREMENT
(FR) DISPOSITIF OPTIQUE DE MESURE
(JA) 測定用光学装置
Abstract:
(EN) A tristimulus-value photoelectric colorimeter is provided with an objective lens (21) on which light from a measurement subject is incident, a photoelectric conversion unit (25) for converting received light to an electrical signal, a luminous flux dividing member (24) for guiding light incident from the objective lens (21) to the photoelectric conversion unit (25), and a control unit (36) and a power source unit (37) which are disposed about the optical axis of the luminous flux dividing member (24) and offset from each other in the circumferential direction. Through such a configuration an optical device for measurement is provided whereby a decrease in measurement precision due to heat from an electronic component is suppressed.
(FR) L'invention concerne un colorimètre photoélectrique à valeurs trichromatiques qui comprend un objectif (21) sur lequel une lumière provenant d'un sujet de mesure est incidente, une unité de conversion photoélectrique (25) pour convertir la lumière reçue en un signal électrique, un élément de division de flux lumineux (24) pour guider la lumière incidente de l'objectif (21) à l'unité de conversion photoélectrique (25), et une unité de commande (36) et une unité de source d'alimentation (37) qui sont disposées autour de l'axe optique de l'élément de division de flux lumineux (24) et décalées l'une de l'autre dans la direction circonférentielle. Grâce à une telle configuration, un dispositif optique de mesure est fourni, par lequel une diminution de la précision de mesure due à la chaleur provenant d'un composant électronique est supprimée.
(JA) 三刺激値型光電色彩計は、被測定物からの光を入射させる対物レンズ(21)と、受光した光を電気信号に変換する光電変換部(25)と、対物レンズ(21)により入射された光を光電変換部(25)まで導光する光束分割部材(24)と、光束分割部材(24)の光軸の周りに配置され、かつ、互いに周方向にずれて配置された制御部(36)および電源部(37)とを備える。このような構成により、電子部品の発熱に起因した測定精度の低下を抑制する測定用光学装置を提供する。
