Binocular microscopes
A binocular microscope refers to any microscope with two eyepieces. Compound or high power microscopes typically have two eyepieces which view images through a single high-power objective lens. The image presented to each eye is a flat, 2-dimentional 'mono' image. It is therefore also possible to have single eyepiece compound microscopes, which are typically very low cost systems used for educational purposes.
