Precitec’s high-precision point sensors based on chromatic confocal or interferometric measurement technology enable non-contact optical thickness measurement, optical distance measurement, and optical topography measurement. Their extremely high lateral and axial resolution and robust applicability under widely differing conditions make them a versatile tool in industrial production. The varied applications for these point sensors range from quality control in the production of glass bottles to silicon wafer treatment in the semiconductor industry.
The CHRocodile CLS line scan sensor is the ideal tool for precise 3D inline inspection in industrial manufacturing applications. The sensor delivers ultra-precise distance and layer thickness data of the sample along a line. The 3D structure of your sample is determined in a very short time through fast line scanning. The line sensor’s chromatic confocal measurement technology supplies data of extremely high lateral and axial resolution, enables measurement of any kind of material, and functions without shadowing effects – even for complex geometries. Typical applications for this line scan sensor include measuring displays or determining the topography of semiconductor chips.
Our multipoint sensors use chromatic confocal measurement technology to simultaneously measure layer thicknesses or distances in multiple positions. Multipoint sensors are thus well suited to measuring large-scale objects such as automotive windshields in automotive industry or flat glass. The simultaneous deployment of up to 96 individual optical probes enables a very flexible application for various geometries and makes for shorter measurement times than conventional single-point sensors.
Precitec’s area scan sensor combines the advantages of an ultra-precise interferometric point sensor with flexible 2D scanner optics. Selective scanning of your sample with custom-designed scanning patterns ensures that only the relevant areas of the sample are measured. This saves you time in inline or offline quality controls. Typical applications for this area scan sensor include quality control in smartphone production, for measuring of camera module step height or lens tilt measurement in a smartphone camera objective. Further applications of the Area Scan Sensor are quality control in display production or measuring electronic components in semiconductor industry.
As our line scan camera uses chromatic optics for 2D imaging, it differs from conventional microscope cameras by offering an extremely high depth of field while maintaining a high lateral resolution. Consequently, this 2D camera works without autofocusing, which saves valuable time during quality inspection. Typical applications include cosmetic inspection for example of smartphones, displays, or quality control of lenses and IOL´s.
The Precitec FocusFinder serves as a focus monitoring system during laser welding processes and uses confocal measurement technology to check any deviations between the sample position and the laser focus. FocusFinder can be used for quality control purposes, as well as for optimizing welding processes and helping to reduce resultant waste. FocusFinder is typically used in combination with optical scanning equipment in the consumer electronics and automotive industries. Moreover, FocusFinder is well suited for combining with other products such as the Laser Welding Monitor (LWM).
Refractive laser-supported eye surgery is an indispensable means of treating vision defects like Hyperopia or Astigmatism. Despite all the advances in surgical techniques the involuntary and uncontrollable movements of a patient’s eye will never change. The laser has to follow these movements with minimal delay to be successful. In view of the increasing quality and customization demands from surgeons and patients, refractive eye surgery is more challenging than ever before. The active Eye Tracking from Precitec with precise tracking in up to 6 dimensions is the solution.
