In the past, a 100x microscope was usually used for measurement, which resulted in large measurement errors and the microscope needed to be readjusted after each measurement. This resulted in low accuracy, cumbersome adjustments, and low efficiency. In addition, the use of reports to save data made data tracking difficult and easy to lose, posing a challenge to production management. With the development of science and technology, line width and line spacing measuring instruments are currently commonly used to achieve digital storage. The measurement of line width and line spacing is based on red light LD positioning technology, which is a technology that uses a laser beam emitted by a red laser diode for positioning, making it easy to find and track.
