Observation optical system, observation equipment, observation training system, and procedures for adapting the observation optics system

摘要

An observation optical system, comprising: an objective lens system (G1) and an imaging lens system (G2), successively from an observation object side, the imaging lens system (G2) being an observation object image formed by the lens system (G1) on an image level of an image sensor, where one of the following conditions is fulfilled:$4000\text{Y/P}\times \left|\mathrm{\beta }\right|32000$where:Y: is a length of one half of a diagonal length of the image plane,P: a pixel stand on the image level; andb: is a lateral enlargement of the imaging lens system (G2).
