Fizeau Interferometer for Optical Testing

Fizeau interferometers are a common type of optical metrology devices in the 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 can be shown that the resulting interference fringes are sensitive to the surface profile.
