  • Precaution while using Microscope

    Respect the light source

    Another microscope safety step that is important to follow has to do with the light source. If the microscope uses a mirror, one should never use direct sunlight to light a specimen, as it can cause severe damage to the eyes. Protect your eyes by following this rule! When it comes to lighting, its a good practice to shut off the light when not in use. This will save energy, protect the specimens, and improve the longevity of the microscope. It will also keep the light from getting too hot to the touch.
