Fizeau Interferometer for Optical Testing

Abstract


Fizeau interferometers are a common type of optical metrology device in industry, and they are often used to test the quality of optical surfaces with high precision. With the help of the channel configuration in VirtualLab Fusion, we build up a Fizeau interferometer, and use it for testing different optical surfaces e.g. cylindrical and spherical ones. It is shown that the resulting interference fringes are sensitive to the surface profile.

Channel Settings for Non-Sequential Tracing

With the flexible channel configuration in VirtualLab Fusion, one can easily control the response of any surface and/or region, to realize the desired model

Use Case

Laser-Based Michelson Interferometer and Interference Fringe Exploration

A Michelson interferometer is set up with the help of non-sequential tracing technology in VirtualLab Fusion, and the interference fringes in different configurations are demonstrated.

Use Case

Mach-Zehnder Interferometer

We build up a Mach-Zehnder interferometer in VirtualLab Fusion and demonstrate how the tilt and shift of component affect the interference fringe.
