[0054] Table 1 lists the detailed information of an electronic viewing window according to an example of the present invention, which includes the radius of curvature, thickness, refractive index, Abbe number, focal length (effective focal length) of each lens, and the like. The surface codes of the lenses are arranged sequentially from the observation side to the image side, for example: "S1" represents the aperture stop S, "S2" represents the surface of the first plane lens C1 facing the observation side, and "S3" represents the first plane lens The surface of C1 facing the image side, "S4" represents the surface of the first lens L1 facing the viewing side, and so on. In addition, the surface "OBJ" is a virtual surface, and its thickness is defined as the distance between the virtual surface OBJ and the aperture stop S (that is, the pupil of the observer). If the thickness is negative, it means that the surface of OBJ is in front of the pupil. If the thickness is A positive...
