Overview
OptoComb, Inc. (株式会社OptoComb) is a Japanese technology company based in Sumida, Tokyo, that develops and sells optical-comb (光コム) generators and their industrial applications, most notably high-speed, high-precision 3D sensors and automated visual inspection systems for manufacturing lines. The company was founded in April 2002 as a technology venture originating from Tokyo Institute of Technology (described on its own history page as the university's 12th venture). It began selling optical-comb generators, optical frequency counters and frequency-stabilized light sources in 2006, and in 2016 released what it describes as the world's first 3D shape measuring instrument using optical-comb technology, which has been widely adopted for automotive-parts appearance inspection. The company has changed its name twice: it was renamed 株式会社光コム (Hikari Com) in 2006, then 株式会社XTIA in 2020, and finally 株式会社OptoComb in January 2024, when it also moved its headquarters to Sumida Ward, Tokyo. Its product line combines hardware and software: optical-comb generators, optical-comb 3D sensors, and a family of inspection machines such as the Optocomb SA top-surface inspection system, Optocomb HS inner-surface inspection system, OptoComb AIC S and AIC R camera-plus-AI inspection systems, OptoComb 360 outer-perimeter inspection, OptoComb VM inner-dimension inspection, OptoComb MPV multi-point vibrometer, and OptoComb XL large optical-comb 3D sensor, supported by software including OptoComb Elements, Scaler, Scan, Sequence Controller, SDK and custom software. OptoComb positions its technology around the concept of "all-piece, 3D, quantitative" inspection — enabling in-line automated appearance inspection of complex-shaped workpieces that are difficult to inspect with conventional methods. Its optical-comb 3D sensors are marketed for coaxial optical measurement, long working distance, 500 kHz high-speed data acquisition and 1 μm height resolution. The company lists major customers and partners including Nikon, Toyota Motor, Nissan Motor, Mazda, Suzuki, Mitsubishi Heavy Industries and IHI. It is a private company with stated capital of 353,882,500 yen, led by representative director and president Hiroshi Fukuzawa, with director and honorary fellow Motonobu Kourogi (Doctor of Engineering) among its officers.
History
OptoComb, Inc. was founded in April 2002 as a technology venture originating from Tokyo Institute of Technology, described on the company's own history page as the university's 12th venture. Its founding purpose was the application and advancement of optical-comb (光コム) technology — a Nobel Prize-recognized field of precision metrology — for industrial use. In April 2006 the company began selling optical-comb generators, optical frequency counters and frequency-stabilized light sources. In July 2006 it changed its corporate name to 株式会社光コム (Hikari Com). In October 2007 it relocated its head office to Chiyoda Ward, Tokyo. A major product milestone came in April 2016 with the release of a 3D shape measuring instrument, which the company describes as the world's first 3D shape measuring instrument using optical-comb technology; it has been widely used for automotive-parts appearance inspection. In November 2017 the company received the Kuramae Kogyokai (Tokyo Tech alumni association) Venture Award, and in the same month it was reported as holding the top share in the automotive-parts appearance inspection market in a Fuji Keizai report. In February 2018 it won the Venture Award 2018 (SME Support Japan Chairman's Award), and in July 2018 it received the semi-grand prize at the IoT Promotion Lab. In February 2020 the company changed its name from 株式会社光コム to 株式会社XTIA, and in July 2020 it moved its head office and demonstration room to a new office in Shinagawa Ward, Tokyo. In July 2022 it received an Excellence Award at the 2022 Laser Society of Japan Industry Award. In January 2024 it changed its name again, from 株式会社XTIA to 株式会社OptoComb, and relocated its head office to Sumida Ward, Tokyo, where it is based as of the company's current disclosures. Throughout this period the company expanded its product family from optical-comb generators and sensors into complete inspection systems — top-surface, inner-surface, outer-perimeter, inner-dimension and multi-point vibration measurement machines — and added AI-based camera inspection and robot-arm integration, alongside a software stack for scanning, scaling, sequencing and custom development. Its stated mission is to continue developing optical-comb technology for diverse industrial applications and to deliver products and services that exceed customer expectations in manufacturing.
