USEOFTHELIGHTMICROSCOPE
USE OF THE LIGHT MICROSCOPEEach time the microscope is to be used it should be set up correctly to give a good image. Most often users forget to adjust the iris diaphragm and focus the condenser to give its optimum performance, this could result in objects in the preparation being undetected.There are many microscope set up procedures for specific functionality but the most versatile for general use is ‘Critical Illu......阅读全文
