ABSTRACT:
An oblique viewing system is attachable to a microscope to selectively obtain a perpendicular view (along the optical axis of the microscope) and oblique views of surfaces of objects under inspection. The attachment is connected to the microscope's objective end by a coupling on a housing containing the viewing system. The system includes a folding mirror and an oblique viewing mirror, spaced from the folding mirror and having its reflecting surface facing the object under inspection. A latching or a toggle mechanism, connected to a rotatable support for the folding mirror, enables that mirror to be set in either of two positions, one out of the way of the perpendicular path to provide a perpendicular view and the other to orient the reflecting surface thereof to face the reflecting surface of the oblique viewing mirror along an optical axis there between. The oblique viewing mirror is supported in a mechanism which enables rotation and translation thereof so as to maintain the optical path to the microscope approximately the same over a range of oblique viewing angles to the surface of the object under inspection. A lens movable along the optical axis between the mirrors adjusts the focus to accommodate different vertical heights of the surface under inspection. By virtue of this lens and the mechanism for orienting the viewing mirror, focusing adjustments of the microscope are made unnecessary.
