を照射し、照射角度が検体に対し一定の角度を有
し、検体の表面に到達する付近に光束が集光結像
するように設定し、結像する光束の幅を表面反射
光と裏面反射光との間隔より狭く定めることによ
り表面反射光と裏面反射光とを分離し両反射光の
中間部に刃先を持つ遮板を置いて表面反射光を遮
断し裏面反射光のみを捕促し検出することを特徴
とする検体の裏面反射測定装置。 The light emitted from the light source passes through a narrow gap and illuminates the specimen using a condensing system, and the irradiation angle is set at a constant angle to the specimen, and the beam is set so that it is focused and imaged near the point where it reaches the surface of the specimen. Then, by setting the width of the light beam to be imaged narrower than the interval between the front reflected light and the back reflected light, the front reflected light and the back reflected light are separated, and a shielding plate with a cutting edge is placed between the two reflected lights. A back reflection measuring device for a specimen, which is characterized by blocking the front reflected light and capturing and detecting only the back reflected light.
