Optical element for measuring information of living body and device for measuring information of living body using the optical element
First Claim
1. An optical element for optically measuring information of living body, comprising:
- a light incident surface, a contact surface contacting said living body and having a groove to protrude said living body, and a light emission surface, for applying a light incident from said light incident surface to said living body, receiving a light absorbed and scattered by said living body, and emitting the received light to the outside from said light emission surface, wherein a light transmittance controlling means is provided at said groove, and said light transmittance controlling means is formed, from a bottom part of a valley part of said groove, on at least a part of a wall surface of said light incident surface side and/or said light emission surface side of said groove.

Abstract
The present invention provides an optical element for measuring information of living body for noninvasively measuring a body fluid component in a test sample of living body with high accuracy, stability, and ease. The optical element includes a light incident surface, a contact surface contacting living body and having a groove to protrude living body and a light emission surface, in which a light incident from the light incident surface is applied to living body, and the light absorbed and scattered by living body is received and emitted from the light emission surface, a light transmittance controlling means is formed from the bottom part of the valley part of the groove, on at least a part of a wall surface of the light incident surface side and/or on a wall surface of the light emission surface side of the groove.
