1. Describe, in detail, how to successfully get an image into view. Be as detailed as you can.
-In order to get an image into view you must first control lighting by turning switch on. Then pick a slide, then select the lowest ocular power (4x) to set microscope into low power. The reposition slide into the circle of light by turning the two knobs located at the right of the microscope. The top knob moves slide back and forth, where as, the bottom knob positions the slide from side to side. Then adjust the focus using the coarse focus and fine focus knob, using the coarse focus first causing a move rapid movement. ALWAYS make sure the microscope is in its lowest power when using the coarse focus knob. Then click switch views to look into microscope. When looking through the microscope adjust the ocular lens until the two circles of light emerge as one.
Adjust the coarse focus down until specimen appears. Use the fine focus knob for clarity of the image, xy controls to get the area of interest into view, and the iris to control the brightness of the image. Once image is focused the objective lens may be changed and you can then begin to view the specimen within a higher power of magnification.
2. Describe the purpose of each of the following microscope parts: ◦ objectives- to magnify the view of each specimen
◦ rheostat Wheel- regulates the light intensity
◦ course and fine adjustment knobs- coarse knob is used for focusing the specimen and the fine adjustment is used for fine tuning the specimen after the coarse knob is used and specimen is focused.
