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.

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.
