white light scatter-plate interferometers. While all three of these interferometers work with a white light source, only the first, the diffraction grating interferometer, is truly achromatic. [8] Here the vertical scanning or coherence probe interferometers are discussed in detail due to their extensive use for surface metrology in today’s ...
A white light scanner (WLS) is a device for performing surface height measurements of an object using coherence scanning interferometry with spectrally-broadband, "white light" illumination. Different configurations of scanning interferometer may be used to measure macroscopic objects with surface profiles measuring in the centimeter range, to ...

Zygo Corporation, or simply Zygo, is a manufacturer headquartered at Middlefield, Connecticut, that specializes in optical systems and equipment.Their metrology product lines include 3D measuring microscopes using coherence scanning interferometry, laser Fizeau interferometers for testing optical components, laser displacement interferometers, and heterodyne optical encoders for stage position ...
Figure 1. The light path through a Michelson interferometer.The two light rays with a common source combine at the half-silvered mirror to reach the detector. They may either interfere constructively (strengthening in intensity) if their light waves arrive in phase, or interfere destructively (weakening in intensity) if they arrive out of phase, depending on the exact distances between the ...

Kind of like the one that just went to Baltimore, Tyler O’Neill. The Red Sox are now a little too left-handed, and stuck with their Masataka Yoshida commitment for three more seasons.
The figure shows the optical path of a Mirau-interferometer. Reference beam (5-4-6) and object beam (5-7-6) have identical optical path length and can thus cause white light interference. Parts of the Mirau interferometer: 1. Lens of the microscope, 2. Semitransparent mirror, 3. Object surface, 4. Reference mirror with reference beam, 5.
