Pratt & Whitney laser-based measuring systems use laser interferometers to deliver exceptional precision and accuracy. Laser Interferometers ZYGO laser interferometers support and enable the most demanding metrology applications in industries from semiconductor and lithography to space-borne imaging systems, cutting-edge consumer electronics, defense-related IR and thermal imaging systems and ophthalmics. When built into manufacturing and inspection equipment, a laser interferometer system reports the position or controls the motion of a product platform with more accuracy than any other method. Laser Interferometers and Calibration Systems Keysight’s laser interferometer and laser calibration systems offer high precision in a wide dynamic range, the ability to measure a position with multiple degrees of freedom, and the highest accuracy available in both air and vacuum systems. ZYGO, long recognized as the world leader in interferometric testing instruments, has designed and built many specially-equipped interferometer systems, including NIR, SWIR, MWIR and LWIR wavelengths. Precision laser interferometric length measuring system as a measuring or calibration instrument for measuring and positioning stages, microscope stages, measuring machines, machine tools, hardness and materials testing instruments Multiple coordinate measurements, e.g. on planar tables Calibration of length measuring instruments

Laser Interferometry is a mainstay of modern physics, belonging in every physics teaching lab. With this experiment, students assemble and align the interferometer themselves, learning about modern optical components, mounting hardware, and alignment procedures. They observe the interferometer fringes first hand (e.g. the image at right), plus they send the beam to a photodetector, modulate Theory Construction of real interferometer Theory Displacement measurements with the use of a laser interferometer allow obtaining the accuracy of a displacement measurement of 0.4 ppm in air and 0.02 ppm in vacuum. The interferometer was first built by A.A. Michelson in 1881. The simplified schematic of the interferometer is shown in the figure below.… Read More »Laser displacement Precision stabilised laser source. The system design uses the Renishaw XL-80 laser interferometer to compensate for Abbe errors in the measurement system relating to any kind of angular displacement incurred in the setup.

Some systems locate the interferometer/beam splitter within the laser head. Thermal growth of the laser head changes the measurement path length, so additional warm-up time is needed before accurate measurements can be taken. By using a remote beam splitter, Renishaw avoids this problem. Calibration of laser interferometer at The National Laboratory. Instrument.

The basic configuration of a Michelson laser interferometer is shown at right. It consists of a laser, a beam splitter, a series of mirrors, and a photodetector (the black dot) that records the interference pattern. What is an Interference Pattern? To better understand how interferometers work, it helps to understand more about 'interference'. Laser Interferometers ZYGO laser interferometers support and enable the most demanding metrology applications in industries from semiconductor and lithography to space-borne imaging systems, cutting-edge consumer electronics, defense-related IR and thermal imaging systems and ophthalmics. Laser interferometry in space is immune form seismic noise and allows for investigation of the frequency range from 0.1 mHz to 1 Hz. The LISA interferometer is a Michelson made of three spacecraft 5 × 10 6 km distant from each other at the vertexes of an equilateral triangle. Laser interferometers are precision measuring instruments for measurement and calibration of length, angle and straightness in wide measuring ranges with high resolution and certainty.

Generic metrology and measurement technology. Delivery level. National Measurement Centre In an interferometer, two identical beams of light, typically but not always from a laser source, are split into two different legs and then recombined.

The high humidity at the measuring location of about 100% and the long stand-off distance of the reflector cause main problems for the interferometer design.
