Stereomicroscopes offer the great advantage of providing a three dimensional view of the sample. This is vitally important for understanding or inspecting microscopic structures, their spatial extent and nature. Stereomicroscopes are therefore indispensable in a huge number of applications ranging from industrial production, quality control and materials research to forensics, biotechnology, genetics and nearly all areas of biomedical research. Modern stereomicroscopes are based on a modular design, allowing them to be configured for individual applications and tailored to the ergonomic needs of the user.
