1. A camera configured to capture an optical image of a target area, the camera comprising:
a lens configured to receive light from the target area;
an imager that has a curved portion convex in a direction away from the lens, the imager being configured to capture the optical image formed on the curved portion by the light that passed through the lens;
a light transmitting material that optically couples the lens and the imager, the light transmitting material transmitting the light from the lens toward the imager; and
a seat having
a support that supports an outer rim of the imager, and
a fluid space defined inside the support, a heat dissipation fluid undergoing convection in the fluid space, wherein:
the curved portion is interposed between the light transmitting material and the seat,
a surface of the light transmitting material from which the light is output is directly stacked on a surface of the imager to which the light is input,
the light transmitting material is made of glass, and
the light transmitting material has a thick plate shape and is sandwiched by the lens member and the imager.
