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 non-sequential tracing 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.
