COLLIMATED INTENSIFIED VISION SYSTEM AND METHOD OF COLLIMATING

摘要

An optical system includes an optical assembly frame having an input portion, an output portion, and an objective lens assembly disposed at the input portion of the optical assembly frame. The objective lens assembly has an objective lens central optical axis. An eyepiece lens assembly is disposed at the output portion of the frame. The eyepiece lens assembly has an eyepiece lens central optical axis parallel to the objective lens central optical axis and offset from the objective lens central optical axis by a distance. An inverting image intensifier is disposed between the objective lens assembly and the eyepiece lens assembly. The image intensifier has an image intensifier optical axis parallel to the objective lens central optical axis and parallel to the eyepiece lens central optical axis. The image intensifier optical axis is offset from both the objective lens central optical axis and the eyepiece lens central optical axis by about half the distance.
