How to use a compound microscope Set your microscope on a tabletop or other flat, sturdy surface where you will have plenty of room to work. Plug the microscope's power cord into an outlet. Switch on your microscope's light source and then adjust the diaphragm by sliding the lever till the most light comes through. Rotate the nosepiece to the lowest-power objective (4x for 40x magnification). It is easiest to scan a slide at a low setting, since you have a wider field of view at low power. Place a microscope slide on the stage , clipped onto the mechanical stage. A prepared slide works best when you do this for the first time. Move the slide until the specimen is under the objective lens. Adjust the large outer coarse focus knob until the specimen is in focus. Slowly move the slide to center the specimen under the lens, if necessary. Do this turning the slide control knobs if you have a mechanical stage.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
