With High-Speed-Microscopy, large-area objects can be acquired in a very short time on a microscopic scale. In industries such as semiconductors, electronics and biology, the demand for microscopic inspection methods is particularly high, as the increasing inspection of large surfaces requires an ever faster acquisition process.

In contrast to conventional stop-and-go operation, high-speed microscopy allows the object to move continuously during the recording process. This allows the sample to be digitized at very high frame rates - more than 100 fps depending on the camera. Synchronous flash illumination avoids motion blur. During the continuous scanning process, real-time hardware autofocus systems automatically adjust the focus so that the sample is sharply imaged at any point. The individual images are stitched together by an efficient stitching algorithm to form a high-resolution, large-area overall image.

Software for real-time data acquisition with RAM recording, which was developed at the Fraunhofer IPT specifically for high-speed microscopy, ensures that image preprocessing and stitching run without delay thanks to GPU processing. The images can be automatically evaluated using specially developed image processing algorithms. Current developments are aimed at the use of machine learning methods such as Deep Learning using Convolutional Neuronal Networks (CNN).

Although the process is already around 30 times faster than comparable stop-and-go methods, the Fraunhofer IPT is working on accelerating the recording process even further. To this end, in addition to constantly improving the software, new components are regularly integrated, such as flash illumination, sensor technology for the hardware autofocus system and camera technology.

Electronics and
wafer manufacturing

With the individually adaptable software of the Fraunhofer IPT, both individual assemblies and entire wafers can be examined for microscopic defects and automatically evaluated. Special types of illumination can be integrated.


With phase-contrast-, fluorescence-, transmitted-light- and reflected-light-microscopy, high-speed microscopy can very quickly capture entire cell culture vessels and slides and thus produce a complete image.

Microstructure manufacturing

Large-area microstructures can be scanned very quickly with high-speed microscopy. Inline image recognition is possible.



With »PhaseAdpatS«, a method is to be developed that optically compensates for the meniscus effect in phase-contrast microscopy during image acquisition.


In the »AIxCell« project, we and our partners have developed a software tool that automatically preprocesses cell images so that biological specialists can directly select and use a suitable model.


In the »LIFToscope« research project, we are developing a fully automated system for cell analysis and separation. A laser integrated into the high-speed microscope transfers living cells gently and precisely.


In »JointPromise« we are developing an automated manufacturing platform for the production of functional joint implants.

StemCellFactory/ Discovery

A high-speed microscope allows the complete recording of microtiter-plates in less than one minute. Image evaluation using deep learning already allows the classification of induced pluripotent stem cells.


Phase contrast is one of the most important microscopy methods for making transparent, unstained cells visible. Adaptive phase contrast microscopy magnifies the visible area many times over.
