Micro-Epsilon adopts Aeva precision sensing technology

Micro-Epsilon will integrate precision optical sensing technology from Aeva into its next generation of industrial measurement products, following a supply agreement covering an order for several thousand sensors.

The German measurement specialist intends to incorporate Aeva’s Eve technology into equipment used for factory automation and quality control. The system uses frequency-modulated continuous-wave (FMCW) optical measurement, with a coaxial sensing arrangement intended to support distance and dimensional measurements across different materials and operating conditions.

Aeva confirmed the agreement on 3 November 2026. Neither company has disclosed the precise order quantity, contract value, delivery schedule, or technical specifications of the planned Micro-Epsilon products.

Micro-Epsilon develops sensors and measurement systems for displacement, distance, position, thickness, and other dimensional characteristics. Its equipment is used in automotive production, robotics, electronics manufacturing, semiconductor processing, and industrial inspection.

The company ships more than 100,000 precision sensors annually, according to figures provided in the announcement. The agreement introduces an additional sensing technology into this established portfolio rather than replacing its existing optical and other measurement methods.

FMCW measurement uses a coherent optical signal whose frequency changes in a controlled manner over time. Light returning from the target is compared with a reference derived from the transmitted signal, creating an interference signal that carries information about the optical path length.

The frequency difference between the transmitted and returning signals can be used to calculate target distance. This differs from conventional pulse-based time-of-flight measurement, which determines distance from the elapsed time between transmitting and receiving an optical pulse.

Coherent detection can support highly precise distance measurements, but its performance depends on the characteristics of the optical source, the stability of the frequency sweep, receiver noise, signal processing, and the properties of the measurement target.

Aeva’s Eve technology applies this approach to precision industrial sensing. The company identifies micron-level measurement capability, resistance to interference, and high-speed acquisition among its intended characteristics, although the published agreement does not provide a complete set of performance limits for the products Micro-Epsilon intends to develop.

The coaxial optical arrangement is another part of the technology. Transmitted and received light follow a common optical axis, an approach that can simplify selected measurement geometries and reduce some alignment constraints associated with separate transmission and reception paths.

Its suitability will still depend on the optical configuration and the target being measured. Surface reflectivity, angle, geometry, and motion can affect the amount and quality of the returned signal.

Industrial distance measurement presents different challenges according to the material and application. A highly reflective metal surface can behave differently from a dark coating, a transparent component, or a surface with irregular geometry.

Changes in illumination, background reflections, and mechanical vibration can introduce further measurement uncertainty. Aeva describes its technology as capable of maintaining performance across a broad range of materials, distances, and lighting conditions, but the companies have not published an independent comparative evaluation for the planned Micro-Epsilon sensors.

Measurement speed also requires consideration alongside accuracy. In an automated production line, a sensor may need to capture a moving target and provide a result before the next stage of the process begins.

The interval between acquisition and the availability of a usable measurement can affect whether a system can detect dimensional deviations or make control adjustments within its required operating time.

Faster measurement capability may support additional inspection points or higher production speeds, provided the sensor maintains adequate precision and the surrounding equipment can process the resulting data.

The complete measurement chain includes the optical sensing element, signal processing, mechanical installation, calibration, and the communications interface used to transfer results to the controlling equipment. Performance at the sensor level does not automatically establish the accuracy or throughput of the finished installation.

Thickness measurement introduces additional geometric considerations. Depending on the product and process, thickness may be determined through measurements from opposite sides of a material or through an arrangement that establishes the positions of relevant surfaces.

Suitable calibration and mechanical stability are necessary to ensure that the measurements remain referenced to the correct geometry. Temperature changes, vibration, and the movement of the material can affect repeatability if they are not accounted for in the system design.

These requirements become important in electronics and semiconductor manufacturing, where inspection systems may need to identify small dimensional deviations while handling components with different surface characteristics.

Micro-Epsilon has not identified which of its existing product families will first incorporate Eve. The company has also not disclosed whether the technology will be used in single-point sensors, scanning instruments, multi-sensor arrangements, or a combination of these configurations.

Its selection nevertheless establishes a commercial supply relationship with Aeva, whose technology is already being used in a separate industrial metrology programme involving Nikon.

In April 2026, Nikon Metrology confirmed the commercial deployment of its APDIS MV5X Laser Radar system using Aeva’s Eve sensing technology. That product is intended for automated dimensional inspection in industries including automotive manufacturing, aerospace, and energy.

The Nikon deployment provides evidence that the underlying sensing platform has reached commercial use in industrial metrology. It does not establish the specifications, qualification results, or performance that Micro-Epsilon’s future products will achieve.

Different applications may use the same underlying measurement principle while requiring substantially different optical arrangements, measurement ranges, mechanical packaging, and calibration methods.

Aeva also supplies sensing technology for applications beyond industrial metrology, including automotive and infrastructure systems. The new agreement concerns precision industrial measurement rather than a confirmed deployment of the company’s automotive perception products.

The multi-thousand-unit order establishes a defined supply commitment, although its commercial scale cannot be calculated without the exact number of units, product configuration, and contractual pricing.

Micro-Epsilon’s next development stage will involve integrating Eve into its own measurement hardware and validating the resulting products against their intended operating requirements.

The companies have not yet announced production model numbers, measurement accuracy figures, operating ranges, or release dates. Those specifications will determine how the new sensors compare with Micro-Epsilon’s existing measurement technologies and where the FMCW architecture can be deployed within industrial production systems.
