Abstract
A stereo microscope includes two oculars mounted at one end of a housing and an objective lens mounted at an opposite end of the housing. Between the opposite ends of the housing is a rotatably mounted lens magnification changer with three series of bores extending diametrically therethrough. For each ocular, a line of sight extends to a prism assembly, through one of the bores of a series which contains a lens assembly and through the objective lens. Both lines of sight lie in a common plane. A LED light source is located adjacent the objective lens. Light entering through the objective lens and one of the series of bores in the lens magnification changer is received by a digital camera.
Claims29
A stereo microscope comprising:
- a hollow elongated body having opposite ends and enclosing first and second optical paths extending through the microscope, one of said ends having two oculars, each including an ocular lens assembly, a prism assembly in each optical path adjacent each ocular, a lens magnification changer rotatably mounted about an axis and located intermediate the ends of said hollow elongated body, a first series of bores located about the periphery of said lens magnification changer in a common plane and extending diametrically through said lens magnification changer, a second series of bores located about the periphery of said lens magnification changer in a common plane and extending diametrically through said lens magnification changer, a third series of bores located about the periphery of said lens magnification changer in a common plane and extending diametrically through said lens magnification changer, said second series of bores being axially located between said first and third series of bores of said lens magnification changer, said bores of said first and third series each including a lens assembly, the other of said ends of said hollow elongated body including an objective lens.
A microscope comprising:
- a hollow elongated body having opposite ends and enclosing first and second optical paths extending through said hollow elongated body, two oculars mounted at one of said ends, each ocular including a lens assembly, a prism assembly in each optical path adjacent each ocular, a lens magnification changer rotatably mounted about an axis and located intermediate the ends of said hollow elongated body, a first series of bores located about the periphery of said lens magnification changer in a common plane and extending diametrically through said lens magnification changer, a second series of bores located about the periphery of said lens magnification changer in a common plane and extending diametrically through said lens magnification changer, a lens assembly located in each bore of said first and second series, the other of said ends of said hollow elongated body including an objective lens, a first of said optical paths extending through one of said oculars to one of said prism assemblies, through one of said first series of bores of said lens magnification chamber and through said objective lens, a second of said optical paths extending through the other of said oculars to another of said prism assemblies, through one of said second series of bores in said lens magnification changer and through said objective lens, one or more light emitting diodes located in said hollow elongated body adjacent said objective lens.
A microscope comprising:
- a hollow elongated body having first and second ends and enclosing first and second optical paths extending through said hollow elongated body, an internal mount, located in said hollow elongated body, having a base section extending from a first of said ends toward a second of said ends, two oculars mounted on a first end of said base section and at a first end of said hollow elongated body, a prism assembly located on said base section adjacent each ocular, said base section having a second end opposite said first end, a lens magnification changer located on said base section intermediate said first and second ends, a first series of bores located about the periphery of said lens magnification changer in a common plane and extending diametrically through said lens magnification changer, a second series of bores located about the periphery of said lens magnification changer in a common plane and extending diametrically through said lens magnification changer, said hollow elongated body including an upper housing shell removably connected to said internal mount by fastening means and enclosing said lens magnification changer, prism assemblies and part of said oculars, an objective lens located at said second end of said hollow elongated body, one or more light emitting diodes located in said hollow elongated body and adjacent said objective lens.
