About Us​

LuminaX originated in a lab at Korea University in Seoul, South Korea. “Lumina” means light, and “X” means we are dealing with X-rays, among other things.

Our team has over 20 years of experience in carbon nanotube growth and vacuum electronic devices including cold cathode X-ray sources.

LuminaX’s patented CNT-based electron emitters will be used to make high-performance X-ray tubes for medical imaging applications.
