    How to Use and Adjust a Compound Microscope

    Step by Step.....Safely and Easily

    Here are step-by-step instructions on how to use and adjust a compound microscope:

    1. Turn on the illuminator.

      When using the dimmer, it is best slowly increase the light intensity as the lamp heats up quite quickly.

    2. Place a slide or specimen on the stage with the sample directly above the aperture and, if possible, fasten it to the stage with the stage clips.

      Reminder: A cover slip is always needed to allow for the best quality image.





    3.

    Ensure the iris diaphragm is completely open, allowing the maximum amount of light to reach the slide and the lenses.

    Caution: Do not use the iris diaphragm to control the light, it is to control resolution and contrast - use the dimmer instead.

    4.

    Rotate the nosepiece so that the objective lens with the lowest level of magnification is directly above the sample.

    Reminder: Using lower magnifications first helps to select the part of the specimen of interest and then adjust further.
