Established as Rainbow Optic Korea in 2005, we have been manufacturing essential precision optical components for various industrial sectors, including communication and electronic optics. To enhance our brand image and competitiveness, we changed our company name to 3L-Systems. This name signifies our dedication to being Korea’s premier optics manufacturer and one-stop service provider, with the ultimate goal of evolving into an optical systems company based in optics.

Moreover, we have young talent working overseas with the goal of promoting 3L optical products (3 Lights: UV rays, visible ray, infrared rays) globally, establishing partnerships in places such as the US, Japan, China, and Singapore.

We are deeply committed to high quality, fast delivery, and excellent service at competitive prices. Ensuring quality satisfaction and technological innovation are our foremost priorities to provide the best service to our customers.
