Spring loaded objective lenses will retract if the objective lens hits a slide, preventing damage to both the lens and the slide. The higher power objectives (starting from 40x) are spring loaded. The most common ones are 4X (shortest lens), 10X, 40X and 100X (longest lens). Objective Lenses : Usually you will find 3 or 4 objective lenses on a microscope. To change the magnification power, simply rotate the turret. Nosepiece : This circular structure is where the different objective lenses are screwed in. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage. Mirrors are sometimes used in lieu of a built-in light. Illuminator : A steady light source (110 volts in the US) that shines up through the slide. To get the total magnification level, multiply the magnification of the objective used (ex: 10X eyepiece * 40X objective = 400X total magnification). Other Important Parts and Their FunctionsĮyepieces : The eyepieces are the lenses at the top that the viewer looks through they are usually 10X or 15X. One knob moves the slide left and right, the other moves it forward and backward.Īrm : Structural element that connects the head of the microscope to the base.īase : The bottom of the microscope-what the microscope stands on. If your microscope has a mechanical stage, the slide is controlled by turning two knobs instead of having to move it manually. Stage : The flat platform that supports the slides. Also, it connects the eyepieces to the objective lenses. Tube : Where the eyepieces are dropped in. Head: The upper part of the microscope houses the eyepiece and objective lenses.
