It works by using two separate optical paths instead of just one. Since then, the basic design has remained the same making the stereo unit a favorite in whatever laboratory it hangs its dust cover in.Ī stereo model is an optical microscope that functions at a low magnification.

Hence the stereo scope was brought to life in the scientific community. They inverted the prism, which created an erect image. The Zeiss engineers made some modifications to the microscope design. Greenough was able to talk the Carl Zeiss Company into producing his design. He came up with a unit that would eventually become the forefather of the stereo models that are known today. Greenough was an American instrument maker. It wasn't until 1890 that anyone would achieve the features that the stereo design is known for. However, this still did not produce a true stereoscopic effect. In comparison, Wenham’s microscope used an achromatic prism to split the light beam in the rear of the objective. The resulting unit projected the left image to the right eyepiece and visa versa.įrancis Herbert Wenham designed the next iteration in the mid-nineteenth century. This was actually a pseudo stereo model, as it used supplemental lenses to make the image.

Cherubin d’Orleans came out with a version way back in 1671. The birth of the stereo microscope was filled with several trials and errors. Shown: AmScope Binocular Stereo Microscope

They have lower magnification when compared to compound microscopes, but they also have a longer working distance. It does this with separate objective lenses and eyepieces for each eye. So what makes these units so special? A stereo, or dissecting, microscope provides a three-dimensional view of the specimen. Stereo models function differently, and therefore meet the needs of users in a different way. Yet most people who don’t spend their days in a laboratory probably couldn’t explain the difference between a stereo model and any other kind. The stereo microscope has been around for awhile.
