Abstract
The invention comprises an afocal lens and mirror assembly comprising an objective lens which gathers light from an object and a field lens which transmits light to a driver's eye to provide an image having sufficient brightness, clarity, and accuracy. The light passing between the objective lens and the field lens is conditioned through an assembly of lenses and reflective elements to produce the image.
