Optical Element for Measuring Bioinformation and Bioinformation Measuring Device Using the Same

摘要

To achieve a reliable and easy measurement of a concentration of a target component in an organism, in an optical element including: a first light-entrance plane, a body tissue contact-plane provided with a groove portion to be brought into contact with a body tissue, and a first light-exit plane; the groove portion includes a second light-entrance plane and a second light-exit plane; light that entered through the first light-entrance plane is applied to the body tissue protruded by the groove portion via the second light-entrance plane, and light absorbed by the body tissue and/or scattered, and entered through the second light-entrance plane exits the first light-exit plane; and a normal line of the plane opposing the body tissue contact-plane, and a plane made by a normal line of the second light-entrance plane and a normal line of the second light-exit plane intersect with each other.
