发明名称 Eyepiece lens system
摘要 An eyepiece lens system comprising a first positive lens component and a second positive lens component: the first lens component being composed of a single positive lens element, and the second lens component being composed of a single cemented doublet consisting of a positive lens element and a negative lens element. This eyepiece lens system has distortion which is corrected favorably by selecting an adequate refractive power for a cemented surface of the cemented doublet and is configured so as to have a sufficiently long eyepoint distance.
