The OptiCentric® product group sets the global standard for optical centering testing and manual and automated lens alignment. With an extremely high degree of lens centering measurement accuracy and integrated operation, OptiCentric® systems are indispensable in modern optics productions. Regardless of whether the sample has a small or a very large diameter, works in the visual or infrared spectral range, or must be aligned, cemented, bonded or just measured: the OptiCentric® systems are modularly designed so that the appropriate system can be chosen for the desired applications and samples....

Advantages of OptiCentric® Systems • Highest absolute accuracy of 0.1 µm and highest resolution of the measurement head • Lens centering measurement of all types of optics, in UV, VIS and IR: spherical, aspherical and cylindrical lenses and lens assemblies • Testing of complex lens assemblies with the MultiLens software module • Fast and precise alignment processes, thanks to the OptiCentric® software module SmartAlign • Exchangeable head lenses for virtually unlimited measurement range • Measurement in reflection and transmission • Modular and integrated OptiCentric® accessories • L arge diameter...

Centering Errors of Optics Centering errors have a critical influence on the optical image quality of an imaging system. There is a centering error when the optical axis of a lens does not correspond with a given reference axis. The centering error is then the angle between the optical axis of the sample and the reference axis. An overview of typical assembly and centering errors can be found in the adjacent drawing. Surface tilt error of a spherical surface Shift of a lens Tilt of a lens Cementing errror Tilt of the aspherical axis Center thickness and air gaps are not correct OptiCentric ®...
