Bringing 'Visible Safety' to the Dangers of Invisible Laser Light. Announcing the Portable Laser Detector 'LASERSIGHT' (Patent Pending)

Yamamoto Kogaku Co., Ltd. (Headquarters: 3-25-8 Chodo, Higashi-Osaka; President: Naoyuki Yamamoto), a manufacturer and seller of industrial safety and health protective equipment, various sports eyewear, eyeglasses, and optical instruments, has developed the portable laser detector 'LASERSIGHT' (patent pending) for near-infrared lasers (fiber lasers, YAG lasers). This product will be unveiled at the 'Laser EXPO' held in Yokohama starting Wednesday, April 22, 2026, with general sales scheduled to begin in early May 2026.

In recent years, the adoption of fiber and YAG lasers has been rapidly advancing in manufacturing sites. Leveraging their high-quality, high-precision processing and high output, their use is expanding across a wide range of applications, including cutting, welding, marking, and laser cleaning of metals and resins. The shipment value of production equipment is projected to more than double in 2024 compared to 2014 (*1).

On the other hand, if fiber and YAG laser light enters the eye, it can reach the retina, leading to permanent vision damage such as retinal injury, vision loss, or in the worst case, blindness. Furthermore, reflected or scattered light spreading in unexpected directions can pose a danger to the surrounding area. Since these lasers emit invisible light, it is not easy to grasp leakages outside of controlled areas on-site. Therefore, implementing safety measures has become a challenge.

To address this, Yamamoto Kogaku has developed the portable laser detector 'LASERSIGHT' to identify the presence of invisible laser light leaks on-site and enhance safety measures. This product detects laser light leakage outside controlled areas and provides notifications with a warning sound and an indicator. This enables the early detection of unexpected laser leaks, contributing to the prevention of accidents. It can also be utilized in various on-site scenarios, including safety inspections before work, such as when changing workpieces, materials, or processing conditions.

Since developing and selling Japan's first laser safety glasses about 40 years ago, Yamamoto Kogaku Co., Ltd. has accumulated expertise in the field of laser safety. Not limited to providing protective equipment, the company offers total support tailored to the worksite, including assistance with product selection, post-installation follow-up, and safety awareness activities through seminars.

With 'Comfortable Safety' as its business concept, the company will continue to contribute to the safety and health of workers and the realization of a better lifestyle by developing and providing various safety and health protective equipment, including safety glasses.
