Where can the source of globally recognized measurement technologies be found? Unrivaled Core Technologies of Topcon—Five of Topcon’s leading engineers share insights into the Company’s unmatched expertise in precision optical technology, sensing technology, automation technology, and image processing technology. Through dialogue, they uncover the technologies and philosophies behind their competitive edge.

Strengths in optical technology

With a deep understanding of fundamental technologies such as geometric optics and wave optics, Topcon has continuously adapted and advanced these fundamental technologies to meet diverse applications and targets. In the positioning field, we integrate optical and electronic measurement technologies, while in the eye care field, we deliver highly precise optical designs tailored to a wide range of eye characteristics, such as axial length and refractive errors. Particularly, our active sensing technology, capable of precise tracking of even the moving eye, is the result of many years of development experience. By delivering high-precision testing data with advanced aberration correction and wide-angle imaging, this core technology enables Topcon’s unique approach to “visualization capabilities.”

Strengths in sensing technology

In addition to optical technology, Topcon delivers optimized sensor solutions built on electro-optic distance and angle measurement technologies tailored to diverse environments and applications. These systems achieve sub-millimeter precision even at distances of 100 meters, ensuring reliable performance not only on the ground, but also in the air, as well as under demanding conditions such as vibration and extreme temperatures. Furthermore, the integration of GNSS receivers into chips enables real-time processing of complex positional data. Topcon’s sensing technologies are widely recognized as the driving force behind the next generation of measurement technology.

Strengths in automation technology

In addition to automated measurement technologies that enable reliable data collection, Topcon derives innovation under the concept of “data democratization”—making valuable information accessible to a wide range of users. In the eye care field, our automation technologies streamlined complex clinical workflows, from image capture to diagnostic support through minimal user operation. By integrating motorized precision optics with image processing and AI, it reduces the need for re-imaging, enhances diagnostic efficiency, and improves both operational productivity and the quality of collected data. Furthermore, through external collaboration using standardized formats, the accumulated data sets are effectively utilized to accelerate future technological development.

Strengths in image processing technology

One of our greatest strengths lies in our integrated development approach—combining in-depth expertise in measurement hardware with advanced point-cloud and image-processing technologies to enhance the performance of our proprietary measurement and diagnostic devices. In the eye care field, we combine proprietary image processing technology with AI algorithms to reduce noise and improve the accuracy of lesion detection. By transforming high-quality optical data into clinically valuable information in real time, we elevate the quality of diagnostic support, delivering tangible benefits to both patients and clinicians.
