YNDK Co., Ltd. is headquartered in Daejeon and is a company specializing in ultra-precision optical systems that creates preemptive response technologies that have never been seen before.

We first started developing HUD for automobiles and are carrying out R&D projects with government agencies as the third research institute funded by the Korea Basic Science Institute (KBSI). 

We mainly produce ultra-precision mold cores, mirrors, and lenses, and we also develop and produce reflectors for satellites and optical systems for missiles.

In addition, we produce research equipment such as PMD (Phase Measuring Deflectometry), which measures the surface roughness of metal mirrors, and DPS (Dry Pumping System), which can store and pre-process electron microscope samples in vacuum. We are developing nano-level processing equipment in collaboration with the University of Arizona in the United States.

The entire process of precision parts, from product design, processing, assembly, automatic control, and measurement, is performed by skilled professionals.
