Microscope parts
Base. It supports the weight of the microscope and houses the illumination source, electronics and
control mechanisms.
Eyepiece tube. Combines the eyepiece with the objectives system. Holds the eyepiece, Barlow lens
(below the eyepiece) or a digital camera (in place of eyepiece).
Eyepiece and objective. Consist of lenses that allow magnifying the image. The total magnication
is calculated by multiplying the eyepiece magnication to the objective magnication.
Barlow lens. Is used with the eyepiece to increase magnication. A 2x Barlow lens increases the
magnifying power twice, so you get a wider range of magnications while using the same eyepieces.
Revolving nosepiece. This triple nosepiece with 3 pre-installed objectives allows you to change
objectives smoothly and easily.
Stage. Sturdy and reliable stage with two specimen holders can be used to move your slides while
observing them. The lower illumination light passes through the opening in the middle of the stage.
Diaphragm disk. Is located below the stage and has apertures of various diameter to adjust the passing
light rays. Rotate the disk to select the desired aperture.
Condenser. A system of lenses located below the stage that allows gathering and directing of the light
rays.
Focusing knob. A coarse focusing system allows moving the stage up and down adjusting the sharpness
of the specimen image.
