The patent application (Publication Number: US20240032778A1) discloses an optical system designed for use in an endoscope. The system includes a most proximal lens, an image sensor with light-sensitive pixels, and a reflective prism. The unique configuration positions the image sensor orthogonal to the optical axis, with the active surface facing the reflective prism. The proximal portion of the lens is smaller than the distal portion, allowing for overlapping along the length and height of the image sensor. This design enables the image sensor to be positioned at the focal point of the optical system, enhancing image quality and clarity.

Furthermore, the patent application details the construction of the endoscope itself, which includes a handle, shaft with a distal head, and the optical system within the head. The endoscope may also feature an image processor for further image enhancement. The system's versatility is highlighted by the ability to adjust the position of the image sensor along the optical axis. Additionally, the endoscopic system may include an illumination source to provide adequate lighting for imaging purposes, making it a comprehensive solution for medical professionals requiring precise and high-quality imaging capabilities during endoscopic procedures.
