LAGMAN based on feel not sight. a n U d e z i r o uth io t c u d o r p re t o n s i n d e w o l al THE LIMITS OF HUMAN VISION d e w o l l a Webster defines resolution t o n s i n as the ability of an optical system to o i t c u d o make clear and distinguishable two r p e r d e z separate entities. i r o h t u a n U The approximate field of view of an individual human eye is 95° away from the nose, 75° downward, 60° toward the nose, and 60° upward, allowing humans to have an almost 180-degree forward-facing horizontal field of view. ed a n U d e z i r o uth io t c u d o r p re t o n s i n w o l al Clinical Methods: The History, Physical, and Laboratory Examinations. 3rd edition.

The first operating microscope was poorly w o l l a configured and ergonomically difficult to use. t o n s i n io t c u d In 1991 Gary Carr introduced an operating microscope o r p and ergonomically configured e with Gallileanan optics r d e z i with several advantages that allowed for for dentistry r o th of the scope for nearly all endodontic and easyauuse n U restorative procedures. Anatomy of Dental Microscope The operating microscope consists of three primary ed components: t o n s i n io t c u d o r (1)The supporting structure, p e r d e z i microscope, and (2)The body oforthe h t u a n (3) The light source U w o l al The Supporting Structure a n U d e z i r o uth io t c u d o r p re t o n s i n d e w o l al a n U d e z i r o uth io t c u d o r p re t o n s i n d e w o l al The Main Parts of the microscope can be divided into 4 groups. t o n s i n io 1.Magnification t c u d o r p e 2.
