ABSTRACT:
An optical device includes a first optical element including an incidence plane on which light from an object is incident, the incidence plane being in contact with the surrounding environment; a main body having an inside and housing the first optical element such that the incidence plane and the inside of the main body are hermetically sealed; a second optical element provided in the main body, the second optical element receiving light from the first optical element; and an absorbent member provided in the main body. In the optical device, the absorbent member has a moisture absorptive capacity corresponding to at least an amount of water retention inside the main body.
