Precision Optics

Measuring tasks in the optics industry are a huge challenge for sensors. Shiny and reflective targets often present complex shapes and must be measured with high resolution and speed.

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.

Testing the quality of objectives for microscopy and smartphones
Testing the imaging quality of lenses is based on wavefront measurements on the optical axis and in the field. Furthermore, automated measurement procedures provide information about focal length, chromatic aberration, polarization effects, PSF and MTF.

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.

Measurement of contact lenses
Contact lens manufacturers have a need to conduct various material tests on clear, flexible polymer samples. The material samples must be submerged during testing in a saline solution for hydration.
The highly sophisticated ThruBeam model ODC2600-40 is uniquely capable of making dimensional measurements with high accuracy and speed.

Measuring the refractive data of intra-ocular lenses

When measuring the distribution of the refractive power, the imaging quality and the lens diameter of intra-ocular lenses, measuring systems based on wavefront technology are used. Ergonomic lens handling and high measuring speed play a decisive role here.

Measuring the refractive data of contact lenses
When measuring the distribution of the refractive power, the imaging quality and the lens diameter of soft and hard contact lenses, measuring systems based on wavefront technology are used. Ergonomic lens handling and high measuring speed play a decisive role here.

Adjusting laser systems
In addition to beam parameter measurements, Shack-Hartmann wavefront sensors are also used to adjust laser systems or fiber-optic systems. The advantage here is their insensitivity to vibrations, suitability for different wavelength ranges, as well as their high dynamic range.

Surface inspection of mirrors
For optical components such as mirrors, a high surface homogeneity is required. reflectCONTROL sensors are used to inspect the reflective surfaces. They detect and classify surface deviations on the mirror surface.

Measuring the surface shape of contact lenses and molds
In order to control and optimize processes, the front and back of the contact lens are measured with incident light during the production process. Molds and tools are measured as well as the calculation of tool offsets.

Measuring the curvature of lenses
In order to meet production tolerances, the contour of optical lenses such as eyeglass lenses or objectives is measured using confocal chromatic sensors. 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 highly curved surfaces.
