At Topcon, our core business is founded on the surveying instruments we have manufactured since our founding in 1932 and ophthalmic & medical equipment we introduced to the market following World War II. Since then, we have expanded our business domains through a combination of M&A and alliances, including construction machinery control technology since 1994, precision GPS receivers since 2000, precision agriculture since 2006, and mobile control technology since 2007.
Today, the world is facing an increase in eye diseases due to global population aging, food shortages caused by global population increase, global infrastructure demands and a shortage of engineering personnel to meet that demand, and continued infrastructure deterioration. In the domains of healthcare, agriculture, and infrastructure, we embraces the slogan "Topcon for Human Life" as we work to expand our business by applying Topcon solutions towards resolving societal challenges.
