の光線入射に伴なう瞳孔径または瞳孔面積の変化状況を
赤外線テレeカメラにより撮像する装置において、上記
検査用光線の光源と目との間に検査用光線を上記瞳孔附
近に集束する集束レンズを設けると共に、上記検査用光
線の通路中に半透明鏡を設け、この半透明鏡を介して検
査を受ける目より観察しうる位置に固視標を設けたこと
を特徴とする瞳孔反応検査装置。In a device that makes a testing light beam enter a wide area of the retina through the pupil and images changes in pupil diameter or pupil area due to the incidence of the light beam using an infrared telephoto camera, there is a device between the light source of the testing light beam and the eye. A focusing lens is provided to focus the testing light beam near the pupil, and a semi-transparent mirror is provided in the path of the testing light beam, and the eye is fixed at a position that can be observed by the eye being tested through the semi-transparent mirror. A pupil reaction testing device characterized by having a marker.
