Laser confocal scanning microscopy is a new technology combining modern optics and electronics. The unique feature of point light source and point detecting eliminates out-of-focus blur and spots. Therefore, the axial and lateral resolution of the system is superior and 3-D imaging can be realized by scanning point by point of the object profile. Because of its advantages, confocal measurement technology is widely applied in many fields, such as medical treatment, biology, configuration of substances and micro-electronics.
