Green Optics has joined the project of Science and Technology Satellite No. 3
by designing and manufacturing thermal imaging optical system,
processing lenses and developing assembly of thin film coating.

Based on the experience, we are currently proceeding various development projects
using new materials of a new generation in collaboration with an astronomical
observatory of the United States.

Green Optics has improved about 10 times (RMS 50nm) the existing surface
irregularity (RMS 556nm) through continuous development of SiC polishing technology.

Green Optics is developing world's best class SiC polishing technology through
the introduction of free high-speed aspherical grinding equipment of large optics.
