A stereomicroscope is a type of light microscope used to observe specimens at different magnifications in 3D. Compared to a conventional light microscope, it uses longer working distances, greater depth of field and lower magnification. The stereomicroscope, also called a binocular magnifier, is composed of two separate microscopes - one for the right eye and one for the left eye. This microscope is also characterised by two separate light beams leading into the eye of the observer, with each eye producing a separate image of the object. These two different images are then evaluated by the brain as a whole in the form of a three-dimensional image of the object.
