Description
It's one of the best science toys for kids and one of the most educational and fun gifts!There is a world out there that is all around us and microscopes give us the ability to see the invisible and learn some amazing things about this world and others. The goal for compound microscope is to be the ultimate source for any information on microscopes and microbiology for fun or scientific inquiry. Focusing the Microscope 1. Start by turning the revolving nosepiece (turret) on the compound microscope so that the lowest power objective lens is "clicked" into position. The lowest power objective is the shortest one. This objective is the easiest to focus and center the image in the field of view. 2. While looking at the objective lens and the stage from the side, turn the coarse focus knob so that the stage moves upward toward the objectives. Move it as far as it will go without touching the slide. 3. Now, look through the eyepiece(s) and adjust the illuminator and diaphragm until you attain the maximum, comfortable level of light. 4. Slowly turn the coarse adjustment so that the stage moves down (away from the slide). Continue until the image comes into broad focus. The turn the fine adjustment knob, as necessary, for perfect focus. 5. Move the microscope slide until the image is in the center of the field of view. Then readjust the illuminator or diaphragm in order to attain the clearest image. 6. Once you have attained a clear image, you should be able to change to a higher power objective lens with only minimal use of the focusing adjustment. If you cannot focus on your specimen, repeat the above steps and work from objective to objective until the higher power objective lens is in place.
