<p>PURPOSE: A three dimensional endoscope optical system is provided to easily control an optical axis and obtain a clear three dimensional image of an object by using a main lens. CONSTITUTION: A main lens collimates light from one point of an object in parallel in left and right sides. A relay lens(120) is formed on one side of the main lens and transmits the collimated left and right images in parallel. A focusing lens(130) is formed on one side of the relay lens and fixes or varies the left and right images which are transmitted from the relay lens in parallel. A CCD picks up the image transmitted from the focusing lens.</p> |
