PPT-Microscope Structure

From its humble beginnings the microscope has undergone numerous revisions since Leeuwenhoeks 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 . 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. OCR AS Biology. Unit 1: Cells, Exchange and Transport. Learning objectives.

Since the microscope was introduced biologists have examined the structure of living things. In most cases they have been found to be compose of cells. There are however some strange exceptions to the general cell pattern..
