Interferometer using laser assembly for testing surfaces of optical elements or entire optical systems

摘要

The interferometer involves the emission of linear polarised laser light, and has at least two prisms, a beam divider and a collimator objective which are bonded together to form a single optic component (4). This is arranged between an optical assembly and an optical measuring system. The optical component includes a beam divider (421) arranged between two prisms (420,422). Also two further prisms (424,427) sandwich a collimator objective (431) and a reflection layer (429).
