Application example

Phase Shifting Interferometry

Lasy 633* easily replaces conventional He-Ne lasers, e.g. in phase shifting interferometers. In contrast to the gas laser, which required the reference surface to be moved in l/8 steps for the phase extraction, Lasy 633 can substitute this mechanical motion for an adequate shift of the laser wavelength. This makes Lasy 633 a superior light source for interferometry.


*  “633“ stands for 633 nm - other wavelengths on request


The TEM Messtechnik GmbH is an innovative medium-sized company in Hannover. It was established in 1988 and changed to a GmbH (Ldt.) in 1998. TEM is specialized in converting scientific results and ideas into real-world applications. The development process goes from the first idea to the production-ready solution and includes customer specific adaption of the standard products, new development at the electronic devices, analog and digital solutions, OEM-boards, modular systems or stand-alone devices.
