Abstract
An analysis device includes a substrate including a first surface, and a second surface positioned at a side opposite to the first surface; a light source part located at the first surface of the substrate, the light source part including a quantum cascade laser; a light detector located at the first surface of the substrate; and a wiring part located at the first surface of the substrate, the wiring part being electrically connected with the light source part and the light detector.
Claims11
An analysis device, comprising:
- a substrate including
- a first surface, and
- a second surface positioned at a side opposite to the first surface;
- a light source part located at the first surface of the substrate, the light source part including a quantum cascade laser;
- a light detector located at the first surface of the substrate;
- and
- a wiring part located at the first surface of the substrate, the wiring part being electrically connected with the light source part and the light detector,
- wherein the substrate is transmissive to a laser light emitted by the quantum cascade laser,
- a laser light emitted by the quantum cascade laser travels through the substrate toward the second surface and is emitted outside the substrate from the second surface, and
- the light detector receives a reflected light of the laser light incident on the second surface of the substrate from the outside.
