Microscopes are delicate and expensive instruments they should be handled with utmost care Before you use the microscope your instructor will explain its proper use Following are rule s that will protect the microscope and insure that you can make m This model comes with color corrected infinity optical system (CSIS), a movable large working distance condenser, 45 degree inclined trinocular head, high eye-point Plan eyepieces, infinity long working distance PLAN achromatic objectives and infinity long working distance PLAN phase contrast objectives. This microscope offers nine brightfield magnification powers, 40X, 60X, 100X, 150X, 200X, 300X, 400X, 600X & 900X, and six phase contrast settings, 100X, 150X, 200X, 300X, 400X & 600X. Its 30 watt adopt Kohler illumination system was designed for 90-240V wide voltage power supplies. History. Types. Care. Parts. Focusing. Diggs?. Hans and . Zcharias. Janssen?.

Care. Parts. Focusing. Types of Microscopes. Light Microscope - .  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.. Learning Targets: . I will learn about the proper care of . a compound microscope. I will be able to prepare my own slide (wet mount).. I will learn how to focus on a specimen using each of the lenses.. 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. . 1. Operating a microscope and performing a four quadrant streak manual.

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. When moving your microscope, always carry it with both hands. Grasp the arm with one hand and place the other hand under the base for support.. Compound Light Microscope. The compound light microscope is a common tool in a life science laboratory. A . compound light microscope. is an instrument that magnifies small objects so that they can be seen easily. . - .  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. Depth of . f. ield: small. Magnification. Uses lenses arranged in series, made of optical material that bends light. All magnification takes place via lenses. Uses . diascopic. illumination (that is, light is transmitted through the specimen). Magnification up to about 1000x..
