Introduction to microscope

Those focusing on the oral cavity

1)Mounting systems

Features

-It should position the microscope laterally and horizontally over the surgical field

-Movements to a new location should be easy

-Vertical positioning should allow for coarse adjustment and fine focus

-Microscope should be well balanced in all axial motions

-Adjustments should lock or provide frictional resistance

-Newer microscopes have switches that unlock electro magnetic couplings to make the microscope movable

-Voice activated microscopes have also been developed

2)Stand designs

                i) Rotating arm design

                ii) Cantilever design

                iii) Electromagnetic
