5. What is the position on the condenser wheel for (1) bright field – low 10X lens, (2) phase contrast – high dry (40X) lens, (3) phase contrast – oil immersion (100X) lens, and (4) bright field – oil immersion (100X) lens?
Homework Answers
Condensers are located above the light source and under the sample in an upright microscope, and above the stage and below the light source in an inverted microscope. They gather light from the microscopes light source and concentrate it into a cone of light that illuminates the specimen.
When looking under the microscope we get good images by adjusting the microscope promptly.
In low power objective(10x) the condenser of the microscope is placed below and the light is fully closed.
In high power objective(40x) the condenser of the microscope is placed middle portion and the light is partially opened.
In oil immersion objective (100x)the condenser of the microscope in higher position and the light of the microscope fully opened.
In phase contrast microscope we used high resolution objectives and specialized condenser.widely opened condenser is used

EXERCISE 1: USE AND CARE OF THE MICROSCOPE 13 0 Move the high-dry lens out of position, and place a drop of immersion oil on the area of the slide you are observing. Carefully click the oil immersion lens into position. It should now be immersed in the oil (FIGURE 1.5). Careful use of the fine-adjustment knob should bring the object into focus. Note the shape and size of the cells. Did the color of the cells change with the...
