Method for assembling lens elements

摘要

A set of lens elements is assembled to form a lens by adjusting a first and a second lens element in a spaced apart optical relationship with respect to each other, then affixing the two elements in the spaced apart optical relationship by affixing a lens element holder to at least the second lens element. Further lens elements are assembled in turn and affixed in spaced apart optical relationship to the preceding lens elements to form a finished lens.
