Microscopes

Laboratory microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces. The Body tube holds the eyepiece and the objective lens while the arm is the curved structure which holds the body tube in place. Coarse and fine adjustment knobs adjust the position of the body tube. Objectives hold high or low power lenses (4X, 45X, 60X or 100X for example). Objectives can be changed through a revolving nose-piece. The stage is the flat surface, which holds the sample and a glass microscopic slide can be adjusted via stage clips. The mirror/lamp increases the light shining through the sample and a condenser concentrates and controls this light. Some microscope can be connected to a computer system via USB and have a digital camera that can be used for imaging and analysis via Micro Image Analysis software.

 

A compound microscope has a single optical path while a Stereomicroscope (zoom stereo or dissecting microscope) has two different optical paths which serve for the depth perception and three-dimensional viewing. It is ideal for viewing rocks, crystals, insects, worms and dissection specimens, etc.
