QPL certification is a system in which the US government guarantees the quality only for products that have passed strict local company inspections made of 150 tests and verifications under the supervision of the US government. Yeonhab Precision obtained the certification in Asia for the first time after 10 years of application. In particular, with the successful QPL registration for the first time in Asia, Yeonhab Precision is the first and only company in Asia which got the qualification of marking “MS” with the title of “Korea’s first MIL-DTL connector”. We will provide customers with the best products as we have the sense of the pride of developing the QPL certified connector with our own technology in Korea.

JWGE connector which was derived from the VG95234, was developed for low-voltage/high-current transmission and, when combined, exhibits IP68 water and dust resistance, also exhibiting excellent durability and mechanical performance in a temperature range of 55° to +125°C. These features are applied and utilized in military vehicles and various industrial equipment.

High-power laser weapons targeting objects at 0.5 ~ 4.0km distances require optical components with sub-nm wavefront error precision. Our Company has successfully developed aspherical polishing and high-power laser coating technologies for Ø300 ~ 550mm optical components through defense project experiences. measurement technology 1) Laser Induced Damage Threshold(LIDT) - The evaluation to confirm the durability of optical components is called LIDT (Laser-Induced Damage Threshold), which is defined as "the maximum amount of laser radiation incident on an optical component when the expected probability of damage is zero" (ISO 21254). In other words, it represents the maximum intensity or power of laser that an optical component can withstand, making it a critical requirement in laser weapon systems. - Our company has established LIDT measurement technology and in-house facilities developed in accordance with ISO 21254 standards. When compared with LIDT test results from domestic and international companies during laser weapon system development, we have demonstrated measurement technology and accuracy that meets or exceeds industry standards. While overseas companies require more than one month for verification processes, our company can immediately provide reliable data through our LIDT system. 2) Cavity Ring Down Spectroscopy(CRDS) - When the reflectivity is 99.997%, this may not present significant issues in low-power laser applications. However, in high-power laser components, even the 0.05% of light that passes through the optical mirror can cause problems in vulnerable parts of the system, including rear optical instruments, bonded lenses, and control cables. Therefore, measurement and evaluation methods for high-reflectivity optical mirrors are extremely important. - Currently, the transmittance and reflectance of optical components are generally measured using spectrophotometers, but measuring reflectance levels of 99.5% or higher is not possible with this method. CRDS (Cavity Ring-Down Spectroscopy) technology is required to achieve measurement resolution beyond that of spectrophotometers, and our company has established this system to measure the reflectance of various optical components. This is a critically important technology for responding to high-power laser weapon system development requirements.

Nas-52 or Night Attachable Sight gives law enforcement and military personnel the versatility in operations through attaching simple night vision device prefixed to daytime sight which makes available to engage in surveillance or to acquire targets regardless of ambient light conditions. NAS-52 is a clip-on system designed to mount in front of any kinds of daytime riflescope, and it gives daytime riflescope the night vision capability. Sniper or designated shooter using daytime scope will significantly need this performance for night time operation.

Revolutionary DFOG Technology Boreas takes Fibre Optic Gyroscope (FOG) technology into the next generation with new, patent-pending Digital FOG (DFOG) technology, developed over 25 years with 2 research institutions. This revolutionary DFOG technology combines a specially designed closed-loop optical coil with advanced spread spectrum digital modulation techniques that have never been used in a FOG before. The resulting DFOG offers dramatically improved accuracy, stability, and reliability with significantly reduced size, weight, power, and cost.
