Abstract
An improved system is provided for converting monocular microscopes to the stereoscopic mode with the aid of polarizing filters or color filters. The embodiment of the system illustrated herein includes means by which the specimen under examination can be viewed by stereo projection. The system may include means by which stereo photomicrography on black-and-white or color film can be easily and effectively accomplished; and it may include means for transmitting stereo microscopic images by television.
Claims10
A stereo microscopic projection system comprising the following elements:
- a monocular microscope for examining a specimen;
- a substage condenser included in the microscope on one side of the plane of support of the specimen;
- and objective lens included in the microscope on the other side of the plane of the specimen;
- a light source positioned to direct a beam of light through said substage condenser, said beam being converged by said substage condenser in the plane of support of the specimen for illuminating the specimen, and said beam entering said objective lens as a divergent beam;
- a beam splitter comprising complementary filters located in the light path between the light source and the substage condenser, said beam splitter causing said divergent beam to comprise two disparate aspects of the specimen to cause said objective lens to produce a pair of disparate images of the specimen;
- and means on which the disparate images are materialized.
