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.
