Green Optics' Government-Backed Project for Core Defense and Aerospace Materials on Track

Green Optics announced on the 3rd that, through close cooperation with the government, it is steadily preparing for mass production of MS-ZnS (Multi-Spectral Zinc Sulfide), a core strategic material for defense, aerospace, and space industries.

In December last year, Green Optics was finally selected for the GVC30 (Global Value Chain 30) project, a national strategic support program led by the Defense Acquisition Program Administration. The GVC30 project is a government-led strategic initiative that focuses on nurturing 30 advanced materials, components, and equipment companies with high potential to enter the global value chain. It simultaneously supports technology advancement and mass production system establishment in key areas directly linked to national security and industrial competitiveness, such as defense, semiconductors, aerospace, and batteries, thereby facilitating their direct entry into global supply chains.

Green Optics was selected for this project in recognition of its top-tier technological capabilities and localization competence in the MS-ZnS field in Korea. MS-ZnS is a high-performance optical ceramic material that can transmit both visible and infrared (IR) wavelengths simultaneously, and it is a key component mainly used in strategic defense sectors such as guided weapons, thermal imaging equipment, and surveillance and reconnaissance systems.

With government funding, Green Optics is pursuing the introduction of a Hot Isostatic Press (HIP) system worth approximately 6 billion won. The HIP system removes internal pores in the material to maximize its optical properties. In particular, it is a core facility that upgrades infrared materials (CVD-ZnS) into multi-spectral materials capable of transmitting in the visible light range, enabling both quality stability and mass production of MS-ZnS.

Based on this equipment, Green Optics plans to establish a full-scale mass production system for MS-ZnS and expand the supply of high-quality MS-ZnS used in advanced interception systems in leading global defense countries such as Israel.

A Green Optics official said, "Following our existing Chemical Vapor Deposition (CVD) facilities, the introduction of this HIP system will be an important turning point for us to leap forward as a global specialized materials company," adding, "We will establish a mass production system that can meet the demand from global partner companies and domestic defense firms, thereby enhancing both our corporate value and investor value."
