Ф450mm Large Aperture Horizontal Laser Interferometer
Application Area
Measure the optical properties of materials, such as thickness, distance;
Measure more precise parameters internal materials, such as optical uniformity, refractive index, and
surface smoothness.
Working Principle
Laser interferometer system includes emitting laser, reflector, oscillator, encoder, scanner, as well as
electronic circuits and software system for detection, adjustment and data output.
The laser beam emitted by the emitting laser passes through a reflector and oscillator to form a vertical
or horizontal injection laser beam and a reference laser beam. Then, it is reflected and interfered on the
surface of the object, and is circulated to an external scanner for linear scanning measurement.Based
on the aforesaid scanning results, encoder outputs data. Finaly the computer achieves fast and accurate
measurement and analysis like surface roughness, effective shape, etc.
