Market Definition
Precision measuring instruments reduce measurement-related errors or machining errors in calibration and manufacturing processes. A laser interferometer is one such precision measuring instrument that delivers precise measurements of real-life objects. In most laser interferometers, a laser from a single source is split into two beams that travel in different optical paths, which are then combined to produce interference. Laser interferometers are usually used in ultraprecision machining and manufacturing, ultraprecision positioning control, and many non-contact optical sensing technologies. Laser interferometers are extensively used in research projects and manufacturing plants for the measurement of small displacements, refractive index changes, and surface irregularities.
