“Building a Stronger Korea Through
Ultra-Precision Optics”

Established in 2004, OPTONICS Co., Ltd. is a specialized company in laser optics and ultra-precision sensor optics. Based on ultra-precision polishing, ultra-low-loss and high-durability coating, ultra-precision dimensional control, optical bonding, and integrated optical device manufacturing technologies, we develop and mass-produce advanced optical components for defense, aerospace, and industrial applications. In particular, we have internalized the capabilities required for the design, machining, coating, assembly, and verification of core optical components used in Ring Laser Gyroscopes (RLGs) and Fiber Optic Gyroscopes (FOGs). Through these capabilities, we contribute to establishing a stable domestic supply chain for Korea’s inertial navigation industry. Building on our accumulated expertise, we are also expanding our business into next-generation sensor and laser fields, including diffraction gratings for high-power lasers, fiber-optic sensor modules, PBPDs, ASE light sources, and atomic vapor cells. OPTONICS manages product quality and manufacturing consistency through cleanroom-based production environments and ISO 9001/14001 quality and environmental management systems. Through continuous research and development and investment in advanced facilities, we will provide customers with reliable optical solutions.
