Green Optics possess proprietary CVD-based Zinc Sulfide (ZnS) production technology for defense and industrial multi-wavelength optical materials. We have core technological capabilities to manufacture high-quality ZnS products tailored to meet diverse customer requirements. ZnS Material Optical Performance and Processing ZnS materials produced through CVD processes provide high transmittance exceeding 70% in the SWIR wavelength range (8-12 μm). When these materials undergo additional Hot Isostatic Pressing (HIP) treatment, the crystal structure undergoes recrystallization, improving transmission characteristics to achieve over 70% transmittance in the visible (VIS) wavelength range of 0.45-0.8 μm. This process extends the application range of optical materials previously limited to SWIR and LWIR bands, delivering superior optical performance across multi-wavelength regions from VIS to LWIR. Material Specifications: - STD-ZnS (Standard ZnS Material): Manufactured via CVD process, exhibits transmittance exceeding 70% in LWIR wavelengths (8-12 μm) with high physical hardness (Knoop hardness: 210 kgf/mm²). - MS-ZnS (Multispectral ZnS): Converted from STD-ZnS through HIP processing, extends wavelength range into the visible spectrum. While crystal structure recrystallization during this process reduces hardness somewhat (approximately 150 kgf/mm²), it still meets MIL specifications. This dual-processing approach enables comprehensive wavelength coverage while maintaining military-grade durability standards.

Lumir developed this new on-board computer in cooperation with Korea Aerospace Industries (KAI) for the CAS500-3 (technology verification satellite), which is scheduled to be launched aboard Korea’s fourth Nuri launch vehicle.

Various line up, high torque frameless motor capable of precise speed and position control. Application areas are Collaborative robots, Dog Horse robots.

Our firm offers end-to-end GaN production capabilities, including fabrication, packaging, test, and failure analysis to meet custom requirements. To enable customer designs, a process design kit (PDK) is available with a design manual, sample layouts, and a non-linear device model. Options available include fabrication of customer-designed wafers (“PDK foundry service”) or custom design by TransEON and fabrication according to customer specs (“NRE foundry service”). For either option, volume levels available include pilot/engineering runs, multi-project wafers (MPWs), or full production runs.

Based on the T-50 trainer’s superior performance and an armament storing capability, the FA-50 aircraft is further developed and upgraded with Tactical Data Link, Precision Guided Munitions, and Self Protection subsystem. Featuring a fighter jet-class flight performance, the FA-50 aircraft has been deployed and operated in the Republic of Korea Air Force (ROKAF) since 2013.

The static-dynamic mixer vipro-DUOMIX is perfectly suited for compressible, two-component materials – with very different viscosities, extreme mixing ratios and high-pressure sensitivity. The extended version with optimized mixing blocks for low-viscosity, and high-viscosity materials on either side brings a further advantage: It is ideally suited for materials that are difficult to mix – with different or identical viscosities. A modular design with five different dispenser sizes per side allows complete flexibility. And a wide range of mixing ratios from 1:1 to 100:1. The vipro-DUOMIX can be used for complex two-component applications in diverse industries such as automotive manufacturing, aerospace, or electronics. Irrelevant of whether it is for a dot dispensing, a bead application or for a potting application. Particularly in the production of aircrafts the static-dynamic mixer is used for honeycomb potting or for edge sealing. Special nozzles with adjustable bead width are available for this purpose. A wide range of two-component materials based on e.g., polyether, epoxy resin, silicone or polyurethane can be dispensed in all areas of application. Due to the parallel alignment of the dispensers, and due to a weight-optimized design, the vipro-DUOMIX is very compact – ideal for assembly in robotic cells or for automated applications.
