WEDEL, Germany, Jan. 17, 2011— Measuring lens centering, air spacing and center thickness inside of an assembled optical system is now possible with a single instrument. The OptiCentric 3D manufactured by Trioptics GmbH offers complete optomechanical characterization of assembled optical systems. It integrates various lens analysis technologies and provides a tool for the evaluation of complex optical systems in R&D or routine quality inspection applications in production.
The two-in-one solution for the detailed investigation of assembled objective lenses combines the proven OptiCentric centering error measurement technology with a low-coherence interferometer called OptiSurf, measuring the air gaps between lens surfaces and the center thickness of lenses within the optical system. The cross-interaction of both measurement systems enables fast alignment of the lens system, increases overall measurement accuracy and provides detailed manufacturing quality information.
Centering errors are measured to <0.1 µm, and air spacing and center thickness to <1 µm. The software has a two-level user interface for complex analysis routines in the R&D phase and an intuitive and user-friendly display for operators in the production environment.
OptiCentric determines the tilt and shift in the X-Y direction of the optical system with respect to a reference axis. With the help of the tilt and translation table or other adjusting elements, the system under test is aligned with respect to the measuring axis of OptiSurf, enabling the interferometer to precisely determine the position of the center of curvatures in the Z-direction, the air gaps between lenses and the lens thicknesses.
After the measurements are complete, the data are input into the MultiLens software where the design data of the optical systems are replaced by the real measurement data obtained with OptiSurf.
