4 Overview
4.1 Use
The contact lens detector is mainly used to measure the diameter of the contact lens, the radius of curvature of the optical zone after the contact lens, and the thickness of the contact lens center.
Some geometrical parameters, such as the device can also be used to quickly observe the surface quality and defects of the contact lens.
