PDF-What is a microscope

Theoretically a microscope is an array of two lenses Need of M icroscopy Living organisms cells and their organelles which are too small to be seen with the human eye can only be seen with the aid. 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. We always offer our customers the best quality for the lowest price.

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). . October , 2017. Background Information.
