The design feature of a Common Main Objective microscope (CMO) centers on the refracting action of a single, large diameter objective, shared by two separate channels of lens system. The design system is also know as a parallel microscope; having the two separate channels operating parallel to each other. This design feature guarantees that the […]

The Greenough system designed by Horatio S. Greenough utilizes inclined twin body tubes to produce a zero effect. Both body tube comprises of a separate but similar lens system, each having its own ocular and objective. The major advantage of this constructive design is the high numerical apertures that can be obtained mainly because the […]

The human eyes function together with the human brain to produce the so-called stereoscopic view—the perception of a spatial and three-dimensional image. This effect can be attained by introducing two slightly different images of the same object onto each of the retinas. Because of the fact that the human eye is separated a distance of […]
