video link on the website httpwwwyoutubecomwatchvX w98KA8UqU Warm up Why would we want to use a microscope to see things When would it be better to use a telescope or binoculars Week 12 Day One. 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?.

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.

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). . How to Focus on Specimen. 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.
