What type of interferometer is a Zygo?

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.

What is Fizeau interferometer?

A Fizeau interferometer is a laser interferometer configuration commonly used for measuring the surface shape and transmission quality of optics and optical-grade surfaces. The “test beam” is directed to the test surface, or through a test optic to a high-quality return mirror.

What are the components of an interferometer?

An interferometer is an instrument that compares the position or surface structure of two objects. The basic two-beam division of amplitude interferometer components consists of a light source, a beamsplitter, a reference surface, and a test surface (Figure 1).

What can a interferometer be used for?

Because of their wide application, interferometers come in a variety of shapes and sizes. They are used to measure everything from the smallest variations on the surface of a microscopic organism, to the structure of enormous expanses of gas and dust in the distant Universe, and now, to detect gravitational waves.

What is an optical profiler?

An optical profiler is a type of microscope in which light from a lamp is split into two paths by a beam splitter. One path directs the light onto the surface under test, the other path directs the light to a reference mirror. This interference contains information about the surface contours of the test surface.

How do you pronounce fizeau?

Ar·mande Hip·po·lyte Louis [ar-mahn ee-paw-leet lwee], /arˈmɑ̃ i pɔˈlit lwi/, 1819–96, French physicist.

How does an interferometer measure distance?

Michelson type laser interferometers measure distance by measuring the phase difference between two portions of the same beam, one sent to a reflector at a fixed distance, and one sent to a measurement surface at an unknown distance. As the distance changes, so does the phase of the combined signal.

Can an interferometer be built with satellites?

Made In Space proposes instead equipping satellites weighing roughly 150- to 300-kilograms with technology to manufacture in orbit a 20-meter optical boom interferometer with a modular internal optics bench the firm developed with Lowell Observatory. …

How is surface roughness measured?

With a contact-type roughness meter, surface roughness is measured by tracing the probe across the surface of the target. In contrast, a laser-based non-contact roughness meter emits a laser beam onto the target and detects the reflected light to measure the roughness.
