Green Optics has supportedin processing lens and
developing assembling a thin film coating in the development

of Science and Technology Satellite No. 3
launched in November 2013 and has supported in designing and
manufacturing thermal imaging optical system.
In addition, Science and Technology Satellite No. 3 mounted with an optical lens.

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

Science and Technology Satellite No. 3
Optics

Green Optics has improved about 10 times (rms50nm) the existing shape
accuracy (rms556nm) through continuous development
of SiC polishing technology.

<The early aperture rms 556nm>
<Full aperture rms 50nm>

Edge slope PV 293nm

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