| abstract | Provided is a camera housing capable of satisfactorily correcting chromatic aberration and obtaining excellent image quality in a medium having a higher refractive index than air, such as underwater, without increasing the size of the entire camera and significantly increasing the cost. . Kind Code: A1 A camera housing in which a housing in which a camera is sealed and housed is placed in a medium having a higher refractive index than air to shoot an external subject. It has an optical window WL arranged so as to be located on the optical axis of the lens PL. Then, when the difference between the refractive index of the optical material for forming the optical window WL in contact with the medium with respect to the d-line as the reference line of the medium and the refractive index of the optical material with respect to the d-line as the reference line of the medium is Δnw, the expression Δnw <0 .50 are set, and the optical window WL is configured to have the diffractive optical surface Gf.
