Optotech Targets Physical AI with European Defense Push

Recap

Source: 로봇신문, report of Sept. 29, 2026

According to the report, Optotech, a specialist in optical components, announced on September 29 that it is aggressively expanding its business in the defense, automotive, and robotics sectors. The company stated that this move is part of a broader strategy to capitalize on the "physical AI" era, where AI extends from software into physical machines like robots and vehicles.

A key development cited in the report is a visit on September 14 by a business delegation from the German Trade and Investment Promotion Agency (GTAI) and the Thuringia Economic Development Company (LEG Thuringen). Approximately 20 representatives from 12 institutions in optics, precision mechanics, and aviation attended the meeting to discuss cooperation on optical components. Optotech expects these discussions to lead to increased medium-to-long-term revenue, particularly in supplying optical parts for European defense applications.

In the automotive sector, the company reported that it has been mass-producing camera lenses for autonomous driving for a North American OEM since January of this year. To meet growing demand, Optotech is planning to expand its production lines. The company notes that the optical performance and manufacturing processes required for autonomous driving lenses share a significant common foundation with those needed for robotaxis and humanoid robots. This allows Optotech to serve the physical AI market without building entirely new production lines, thereby improving equipment utilization and profitability as volumes increase.

Context

Thuringia, the German state involved in the delegation, is a major European hub for optics and photonics, hosting over 180 optics companies and 230 electronics/semiconductor firms. The region is known for strengths in infrared imaging, LiDAR, and advanced sensors. Globally, European defense and automotive industries are increasingly seeking to reduce reliance on Chinese supply chains, a trend often referred to as "Non-China" sourcing. Optotech, which operates production bases in Korea, Vietnam, and China, positions its Korean and Vietnamese facilities as key assets for meeting these non-China supply chain requirements.

The concept of "physical AI" refers to the integration of AI models into embodied agents, such as humanoid robots and autonomous vehicles. These systems require high-precision optical components for environmental sensing, making the demand for advanced lenses and filters a critical bottleneck and opportunity for specialized manufacturers.

Robot's take

Optotech’s strategy highlights a significant trend: the convergence of automotive and robotics supply chains. By leveraging existing autonomous driving lens production for humanoid robots, the company is reducing the capital expenditure typically associated with entering new markets. This is a smart move for a component supplier, as it turns a potential market shift into a volume opportunity rather than a risk.

However, the success of this strategy depends on the pace of humanoid robot commercialization. While the technology overlap is strong, the volume of humanoid robots is currently far lower than that of autonomous vehicles. If the "physical AI" hype does not translate into mass production, Optotech may find itself with excess capacity in lines designed for a future that is slower to arrive than expected. The defense sector offer provides a more immediate revenue stream, but the long-term growth story remains heavily tied to the robotics market's maturation.
