Measuring the curvature of lenses
In order to meet production tolerances, the contour of optical lenses such as eyeglass lenses or objectives, confocal chromatic sensors are used. Based on the distance values, statements about the surface properties can also be made. The sensors enable a large tilt angle which means they can also detect ag8亚游集团ly curved surfaces.
Camera auto focus measurement
Confocal sensors measure the distances between the auto focus lenses to provide the camera with the ag8亚游集团est possible image quality.
Surface inspection of mirrors
With optical components such as mirrors, a ag8亚游集团 degree of surface homogeneity is required. reflectCONTROL sensors are used to test the reflecting surfaces of these reflecting surfaces. They detect and classify surface deviations on the mirror surface.

Measuring the center thickness of lenses
In order to meet production tolerances, the center thickness of optical lenses such as eyeglass lenses or objectives is measured using confocal chromatic sensors. The measurement is performed from one side and can also be carried out with very thin lenses.
Nanometer positioning in lithography machines
To illuminate individual components on the wafer, the lithographic devices move the wafer to the respective position. Capacitive displacement sensors measure the position of the travel path in order to enable nanometer-accurate positioning.
