Ultrasonic inspection systems for non destructive material testing (NDT)

Optel provides a wide range of ultrasonic inspection system solutions and technologies, applicable across multiple industry sectors. From standard ultrasonic inspection systems to customized and sophisticated ultrasonic measurement systems for the needs of our customers, fulfilling the most demanding technical requirements. We are following the Industry 4.0 trend towards automation and data exchange in technology and processes within the manufacturing industry, including: IoT, IIoT, AI, as well as smart manufacture and smart factories.

Ultrasonic instruments and devices

The opCard and opBox defectoscopes family with opMux multiplexers are high-performance, precise, multi-channel ultrasonic testing devices, designed for use in ultrasonic NDT systems, but also suitable for other measurements using ultrasonic pulses. Together with the software, with a tailored set of tools for signal visualization and analysis, they offer the best solution for ultrasonic testing. Various configurations allow us to provide a wide range of instruments and systems. Due to their versatility, flexibility and easy-to-use software, opCard, opBox and opMux are ideal for testing: weld inspection for cracks and volume defects, soldered and coated joints for adhesion quality, wall thicknesses, shafts, rods, tubes and sheets as well as plastics or fibre or any ultrasonic material characterization. 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 gaging, measurement of materials properties, medical diagnostics and also in power generation, oil and gas applications and many more. We are offering different types of ultrasonic transducers. Standard options come in many styles, element diameters, frequencies, and connector style. We offer also custom-designed probes. Our high-quality probes and transducers are available in a wide range of frequencies, configurations, connector styles 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 opGen generators family in the power range from 100 to 2000W are designed for the more stringent requirements of high-performance ultrasonic applications. The sophisticated control system is based on the transducer impedance analysis and is done in real time. It always ensures the best working conditions depending on the physical status of the system. The generators transform energy from the electrical supply network into a high-frequency sinusoidal / rectangle / burst or sweep oscillation from 10kHz to 125kHz or 10-100kHz. Real time regulating processes generate optimum ultrasonic oscillations.

Ultrasonic testing scanners

Our scanners are controlled by our software for make the scan that covers the inspection area and to acquires the scan data, required in the customer application. Take advantage of one of our standard scanning solutions, or have us customize a scanning solution to fit your specific needs. We also offers several motor controllers for scanners, depending on the equipment used in the application.

Biometric and Medical application

Since 1989 we were focused on developing ultrasonic fingerprint reader based on ultrasonic holography. This was the reason why we have collected very unique and sophisticated know-how and knowledge in many areas of ultrasonic technology during those years. This is a very good background for developing new and very innovative systems across other medical application such as early detection of breast cancer, ultrasonic holographic scanner for measurement and visualization of teeth, jawbone cavities, holographic sonograph for visualization and monitoring of changes in lung tissues, especially caused by COVID-19 and a lot of others 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 inspection concepts. This may be the final testing in production, serial testing or batch testing on a random basis. Due to single inspection of e.g. prototypes, we support the development and the exclusion of problems for future manufacturing.


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!
