Abstract

During the manufacture of optical coatings, to control the thickness of every layer is very important. Different monitoring methods may make different accuracy. AB method is much advanced in monitoring the thickness. Through the switch of monitoring glass and appropriate choice of wave length, stop point of each layer was located in sensitive position. With AB method, errors was cut in some degree and the influence of refractive index from many factors was lessened by revising stop points.
