Abstract:
A stereoscopic, long-distance microscope apparatus (100) for stereoscopically examining a target (10), said apparatus (100) comprising:a front lens means (14) having a diameter D.sub.fl for receiving light rays from said target (10), said front lens means (14) having an object side surface and an image side surface;a rear mirror means (18) having a diameter D.sub.rm for receiving light rays from said front lens means (14), said rear mirror means (18) having an object side surface that faces the image side surface of said front lens means (14), and wherein the diameter D.sub.fl of said front lens means (14) is less than the diameter D.sub.rm of said rear mirror means (18);a secondary mirror means (22) for receiving light rays from said rear mirror means (18), said secondary mirror means (22) being located on said image side surface of said front lens means (14);an angled-mirror means (24) for receiving light rays from said secondary mirror means (22); and,an eyepiece means (36) for viewing the light rays from said angled mirror means (24), said eyepiece means (36) comprising a stereoscopic eyepiece suitable for use by both eyes,wherein said light rays viewed by human eyes through said eyepiece provide a stereoscopic, three-dimensional view of said target (10) and wherein said target (10) is located within 100 mm to 300 mm of said front lens means (14).
