  • Multiple pass optical system
    Patent number: 4676652
    Abstract: A multiple pass optical system comprising a reflecting objective placed across the path of a radiant flux emitted by an illuminator; the objective being mounted pivotally around its own axis. Further, the radiant flux its incident upon a compound collective comprised of two different-curvature mirrors arranged at right angles to each other.From the lens of the radiant flux, the flux is directed again to the reflecting lens to be reflected therefrom and upon passing the final cycle in the system, it emerges.
