Claims

1. AN ANGLE ADJUSTING MECHANISM FOR AN OPTICAL ELEMENT, COMPRISING:

A FIXED PLATE;

A MOUNTING PLATE POSITIONED SUBSTANTIALLY PARALLEL TO SAID FIXED PLATE AND HAVING MEANS SECURED THERETO FOR HOLDING AN OPTICAL ELEMENT;

AND FOUR PAIRS OF SET SCREWS JOINING SAID FIXED PLATE AND SAID MOUNTING PLATE, TWO OF SAID PAIRS BEING ALIGNED ALONG A FIRST DIRECTION AND TWO OF SAID PAIRS BEING ALIGNED ALONG A SECOND DIRECTION WHICH IS PERPENDICULAR TO SAID FIRST DIRECTION, ONE PAIR OF SET SCREWS ALONG EACH DIRECTION EXTENDING THROUGH SAID FIXED PLATE IN THREADED RELATION THEREWITH AND BEARING AGAINST SAID MOUNTING PLATE WHEREBY ROTATION OF SAID SCREWS EFFECTS MOVEMENT OF SAID MOUNTING PLATE AWAY FROM SAID FIXED PLATE, AND ONE PAIR OF SET SCREWS ALONG EACH DIRECTION EXTENDING THROUGH SAID FIXED PLATE IN TRANSLATION-CAPTURED RELATION THERWITH AND BEING THREADEDLY ENGAGED IN SAID MOUNTING PLATE WHEREBY ROTATION OF SAID SCREWS EFFECTS MOVEMENT OF SAID MOUNTING PLATE TOWARDS SAID FIXED PLATE.
