Abstract

An optical device including a contact part having a contact surface and an opposing surface, the contact surface coming into contact with a test subject and the opposing surface being opposite the contact surface; a support body installed on the opposing surface; a first element supported by the support body; and a second element disposed between the opposing surface and the support body; wherein one of the first element and the second element is a light-emitting element for emitting light towards a detection site of the test subject; another of the first element and the second element is a light-receiving element for receiving reflected light, the reflected light being light emitted by the light-emitting element and reflected at the detection site; and the contact part is formed from a material that is transparent with respect to a wavelength of the light emitted by the light-emitting element.

First claim

What is claimed is:

1. An optical device comprising:
a contact part having a contact surface and an opposing surface, the contact surface adapted to come into contact with a test subject, the opposing surface being opposite the contact surface;
a support body installed on the opposing surface, the support body having a first surface and a second surface, the first surface facing the opposing surface and the second surface being opposite the first surface;
