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). . By: Eric Zunica. NEM 3002 – Principles of Nematology .

Turn on light source on high. Turn the objective to low (4x). Lower the objective lens so that it is close but not touching the slide. Center the image by moving the stage. Adjust the diaphragm for optimum light. - .  the models found in most schools, use compound lenses to magnify objects. The lenses bend or refract light to make the object beneath them appear closer.. Common magnifications: 40x, 100x, 400x. October , 2017. Background Information. The microscope is one of the most commonly used instruments in the medical colleges, and in clinical laboratories. Students of physiology use it in the study of morphology of blood cells and in counting their numbers. . Microscope Review The diagram represents a cell in the field of view of a compound light microscope. In which direction should the slide be moved on the microscope stage to center the cell in the field of view
