What is a Laser measuring machine?

A laser length measuring machine is a length measuring machine that uses a laser as a light source. Since it uses a visible light laser with a wavelength of several hundred nanometers, it is a device that can measure with high resolution of sub micrometer. The laser length measuring machine irradiates the corner cube attached to the sample with laser light and measures the distance to the sample by analyzing the phase difference of the reflected laser light. There is also a laser length measuring machine that can measure the velocity, acceleration, and displacement of a sample by using optional software.

Application of Laser measuring machine

Laser length measuring machine is used for positioning with high accuracy
Laser length measuring machines are used for equipment that requires high-precision positioning, such as semiconductor manufacturing equipment, electrical and electronic equipment manufacturing equipment. In addition, since it uses light, it can also be used to measure the speed and position of chip mounters and printer heads that move at high speed. In addition, by simultaneously measuring the distance between two laser length measuring machines in a moving part such as the stage of the device, it is necessary to confirm the presence or absence of pitching and yawing of the stage and the presence or absence of displacement in the same device. There is also.
