For Set-Up 3 you first size and you then center the Cylinder of Light projected up into the Condenser Lens by the Illuminator. You then remove the Right Eyepiece and perform a final "Trim" on the Cylinder of Light before it is projected into the Condenser Lens, where it is "condensed" into a Cone of Light that is projected onto the Specimen. How do you do this on your Olympus Microscope? Group of answer choices You first use the Field Diaphragm Control to size and then the Condenser Centering Screws to center the Image of the Condenser Diaphragm projected into the Condenser Lens by the Illuminator. You then remove the Right Eyepiece and once again use the Field Diaphragm Control to perform a final "Trim" on this Cylinder of Light.

Unwrap the electrical cord, connect it to the plug it into one of the outlets at your bench, and turn on the illuminator. Adjust the brightness control to a little below full brightness (about 70% intensity). Light intensity is controlled by the dimmer switch, not the iris diaphragm. If the field of view is too bright, the light intensity can be reduced, by adjusting the brightness control. With live mounts this is a necessity. With a low power objective you may have to cut down on illumination intensity. With a high power you need all the light you can get. The iris diaphragm of the condenser is used at higher magnification to improve contrast. While looking through both oculars, adjust the interpupillary distance by moving the ocular objectives closer or farther apart until a single bright circle can be viewed. If the oculars appear dusty or smudged, notify your instructor who will provide you with a cotton swab or compressed air to clean these lenses. Since the oculars are not equipped with protective shields they are likely to become dusty. Do not attempt to clean the oculars with lens tissue. Place the slide on the stage and secure it within the clamps. Adjust the slide so that the specimen is centered over the beam of light coming from the condenser. With the scanning objective (4X; red ring) in place (vertical over the condenser) and the stage elevated to the stop point, look through the oculars and bring the specimen into focus by moving the stage down with the coarse adjustment knob (on left side). Enter the specimen in the field of view by adjusting the mechanical stage (knobs on the right side of stage) without touching either of the focus knobs. Rotate the nosepiece so that the 10X low power objective (yellow ring) is brought into place. View the specimen and use only the fine adjustment to bring the specimen into sharp focus (you should have to turn the knob over the top away from you). The fine adjustment is used to obtain maximum resolution.

Please put the steps for focusing a compound microscope in order, from first to last. Hint: Review the steps on pages 106-107 of your lab manual. Place your microscope on the table and adjust the distance between the ocular lenses. Turn on the light and adjust the level of the light. Focus the light on the stage using the condenser. Use the coarse focus knob to move the stage down. Place the slide of interest on the stage, using the stage clips as shown in Figure 5-4 on page 107 of your lab manual. Center the slide over the light that comes through the stage. With the slide clipped in place on the stage and the 4x objective over the stage, use the coarse focus to move the stage up. Looking through both ocular lenses, lower the stage with the coarse focus until the specimen is in focus. Turn the nosepiece until the 4x objective is in line with the body tube. You will hear a click when any objective lens is in place over the stage. Once the slide is in focus using the 4x objective, move to the 10x objective and adjust the view using the fine focus.

2. Match each part to its function. Stage Stage adjustment knobs Light intensity knob Interpupillary adjustment Coarse focus knob Fine focus knob Iris diaphragm Condenser Condenser adjustment lever Specimen holder Eyepiece length adjustment Electrical cord Closes down the amount of light, and sharpens image. Lifts or lowers the condenser; the closer to the specimen the better. Should be set so that both eyepieces are the same length. Moves a slide side-to-side and front-to-back. Changes lamp brightness. Should only be detached by holding the plug. Aligns light waves before they pass through specimen. Provides flat surface for specimens. Allows both eyes to see an image simultaneously. Holds a slide in place on the stage. Moves the stage up and down in tiny amounts. Moves the stage up and down rapidly. Some microscopes have this length indicated by a white ring, or a white dot, or by a line that is aligned with a "0."
