Ф300mm Large Aperture Horizontal Laser Interferometer
Application Area
Dual port test system；
For measuring surface quality of large aperture optical component；
For measuring optics homogeneity of material；
For measuring multiple surface quality of parallel plate component；
Component surface accuracy analysis and optics date processing.
Working Principle
By emitting two mutually perpendicular interference lines(one is an injection laser beam ,the other is
a reference laser beam ) to point them at object surface (to measure the flat contour). When there
are fluctuations on object surface, the injection laser beam shifts with the change of distance, which
causing the phase change of both beams and forming a laser interference image. Then Combined
with the assistance of a grating ruler or a linear array scanner, parameters information can be obtained,
such as the object surface shape and size.
