From its humble beginnings the microscope has undergone numerous revisions since Leeuwenhoek’s day. But its usefulness has certainly not diminished. Numerous types of Microscopes are currently being used. Visit the following for a more detailed description of them. . Care. Parts. Focusing. Types of Microscopes.

Reutt-Robey. , University of Maryland College Park, DMR 0520471. A microscope technique called “Kelvin probe microscopy” (KPM) is used to map the differences in the electrical potential on the surface of graphene on silicon carbide, shown here as different colors. KPM identifies single layer graphene (SLG), bilayer graphene (BLG), and two types of interfacial layer (IL1 and IL2). . http://biology.unm.edu/ccouncil/Biology_203/Summaries/Microscopes.htm. 1.
