Ultrasonic inspection systems for non destructive material testing (NDT)

Optel offers a wide range of ultrasonic inspection systems and technologies that can be used in various industries. From standard ultrasonic inspection systems to customized and advanced ultrasonic measurement systems for our customer's needs, meeting the most demanding technical requirements. We follow the Industry 4.0 trend towards automation and data exchange in technology and processes within the manufacturing industry, including IoT, IIoT, AI, and smart manufacturing and smart factories.

Ultrasonic instruments and devices

The opCard and opBox family of defectoscopes with opMux multiplexer are powerful, precise, multi-channel ultrasonic flaw detectors designed for use in NDT ultrasonic systems, but also suitable for other ultrasonic pulse measurements. Together with software that includes a set of customized tools for signal visualization and analysis, they provide the best solution for ultrasonic testing. Various configurations allow us to offer a wide range of devices and systems. Due to their versatility, flexibility, and easy-to-use software, opCard, opBox, and opMux are ideal for inspecting welds for cracks and volume defects, solder and coating joints for adhesion, wall thickness, corrugations, rods, tubes, and sheets, as well as plastics or fibers, or for any kind of material characterization with ultrasound. Easy to use as an OEM solution for your inspection systems.

Ultrasonic Transducers and Probes

Ultrasonic transducers are used for applications as diverse as flaw detection, thickness measurement, material property measurement, medical diagnostics, and also in power generation, oil and gas applications, and much more. We offer several different types of ultrasonic transducers. Standard options come in many styles, element diameters, frequencies, and connection types. We also offer custom probes. Our high-quality probes and transducers are available in a wide range of frequencies, configurations, connector types, and cable types to help you meet demanding inspection requirements.

Generators and analyzers for power ultrasound

The opGen high-power ultrasound generators are innovative and technologically advanced. The generators of the opGen family in the power range from 100 to 2000 W are designed for the increased requirements of high-power ultrasonic applications. The sophisticated control system is based on the impedance analysis of the transducer and is performed in real-time. It always ensures the best working conditions depending on the physical state of the system. The generators convert energy from the electrical supply network into a high-frequency sine/square/burst or sweep oscillation from 10kHz to 125kHz or 10-100kHz. Real-time control processes produce optimal ultrasonic oscillations.

Ultrasonic testing scanners

Our scanners are controlled by our software to make the scan that covers the inspection area and to capture the scan data that is needed in the customer application. Use one of our standard scanning solutions, or let us customize a scanning solution for your specific needs. We also offer different motor controls for scanners, depending on the equipment used in the application.

Biometric and Medical application

Since 1989, we focused on the development of ultrasonic fingerprint readers based on ultrasonic holography. This was the reason why we have accumulated a unique and highly developed know-how and knowledge in many fields of ultrasonic technology during these years. This is a very good background for the development of new and very innovative systems for other medical applications, such as early detection of breast cancer, ultrasonic holographic scanners for measurement and visualization of teeth and maxillary sinuses, holographic sonography for visualization and monitoring of changes in lung tissue, especially caused by COVID -19 and many other medical applications.


Research at OPTEL is carried out across a number of different channels in partnership with industrial partners and research and technology organizations, academic institutions and enterprises.

Feasibility Studies

We analyze the testability of your components and create suitable test concepts. This can be final testing in production, series testing, or random batch testing. Through the individual testing of e.g. prototypes we support the development and the exclusion of problems for future production.


We provide our customers with complete technical support, spare part supply as well as repairs and other Systems for all their own and their partners' products. We offer our customers the examination and calibration of ultrasonic instruments and systems according to various standards and inspection requirements. Our high qualified personnel performs the examination with constantly calibrated measuring instruments. All measurements are being documented and summarized in a test report.

Years on the market, since 1989!
