Ocular Separation and Diopter Adjustment Step 1: Focus your sample in bright field. Step 2: While looking through your right eye (cover your other eye or simply close it) focus on a single point in your sample using the fine focusing knob and remember its location. Step 3: Now, while looking through your left eye (cover your other eye or simply close it) focus on the same point as in step 2 using the Ocular Diopter Knob. Step 4: Open both eyes and now you should be able to see a clearer image. You do not need your prescription glasses to continue observing though the microscope. Ocular Diopter Knob Fine Focusing Knob You can adjust binocular microscope to fit the distance between you eyes and to correct for some prescription lenses you may have. To adjust the oculars to your eye-separation simple push the oculars, while looking through them, closer together or farther apart until you see a single image of the object. For Diopter adjustments follow the steps below:
Köhler Illumination Illumination of the specimen is the most important variable in achieving high-quality images in microscopy and critical photomicrography. Köhler Illumination is as a method of providing the optimum specimen illumination. This method guarantees that the condenser is providing the best amount of light possible for the combination of lenses. Step 1: Focus your sample in bright field. Step 2: Close the field diaphragm. Step 3: Focus the edge of the diaphragm by adjusting the condenser height. Step 4: Center the image using the two centering screws. Step 5: Open the field diaphragm until it is at the edge of the field view.
