The stereo or stereoscopic is an optical microscope variant
designed for low magnification observation of a sample, typically
using light reflected from the surface of an object rather than
transmitted through it.
The instrument uses two separate optical paths with two objectives
and eyepieces to provide slightly different viewing angles to the
left and right eyes. This arrangement produces a three-dimensional
visualization of the sample being examined.
Stereomicroscopy overlaps macrophotography for recording and
examining solid samples with complex surface topography, where a
three-dimensional view is needed for analyzing the detail.
The stereo microscope is often used to study the surfaces of solid
specimens or to carry out close work such as dissection,
microsurgery, watch-making, circuit board manufacture or
inspection, and fracture surfaces as in fractography and forensic
engineering. They are thus widely used in manufacturing industry
for manufacture, inspection and quality control. Stereo microscopes
are essential tools in entomology.
