- Preparing a wet mount of the letter "e”. 1. Obtain a prepared ‘e’ slide. 2. Focus the slide first with the scanning objective, then click to lower power and focus again. 3. Finally, focus the slide under high power. Remember, at high power, you should ONLY use the fine adjustment knob. 4. Draw the ‘e’ exactly as it appears in your viewing field for each magnification. The LPO, HPO, and Oil ImmersionTo alter the amount of light coming through the stage someone should adjust the: Group of answer choices 1. eye pieces 2. coarse focus 3. objective 4. iris diaphragm 5. fine focus2. 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 (find the white ring) 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.
