Abstract
With a probe 2 in which an end of the organic photoelectric-conversion layer 23 on a projection optical path 10 side is covered by an upper electrode 24 having a light-blocking effect, light passing through the projection optical path 10 from a light source can be prevented from directly entering the organic photoelectric-conversion layer 23.
Claims6
A probe for bioinstrumentation comprising:
- a transparent substrate having flexibility;
- an organic light-receiving element that is provided on the transparent substrate, includes an organic photoelectric-conversion layer sandwiched between a transparent electrode and an upper electrode, and, when light for measurement is radiated onto a subject, detects scattered light that is scattered by the subject;
- an upper circuit board that has flexibility and is provided on the side opposite to the transparent substrate with respect to the organic light-receiving element, and is provided with wires therein that are connected with the transparent electrode and the upper electrode;
- a projection optical path that is provided apart from the organic light-receiving element and transmits light for measurement along a thickness direction of the transparent substrate, the projection optical path formed as a through hole that penetrates from an upper side of the upper circuit board to a lower side of the transparent substrate;
- and
- a connector that is attached to the upper circuit board and allows the wires to be externally connected, wherein
- the upper electrode has a light-blocking effect and covers an end of the organic photoelectric-conversion layer on the side of the projection optical path.
