VIDEO CAMERA WITH HOUSING FOR UNDERWATER IMAGING

摘要

The present invention provides a housing for use in an underwater video camera which does not require a window comprised from a thick parallel flat plate and large scale pressure resistant sealing container and which can take 3D images in deep water or hadal zone. A housing for an underwater video camera formed from a glass hollow sphere for housing an imaging video camera including filling a roughly spherical segmental shape correction lens to a spherical segment enclosed by a cutting plane parallel to a lens surface of an imaging lens of the imaging video camera housed inside the glass hollow sphere, the cutting plane being a flat surface facing the lens surface and an inner surface of a spherical crown of the glass hollow sphere cut out using the cutting plane.
