    Laser interferometry is a primary technique for measuring the surface quality and transmitted wavefront error of precision optics. While Fizeau laser interferometers are the most widely used commercially, Twyman-Green interferometers have distinct advantages for a variety of applications. Download this article to learn about the two configurations and the applications served by each systems’ particular strengths.
