SGGG crystal, namely Ca Mg Zr doped gadolinium gallium garnet, is an excellent substrate material for Bi Fe garnet epitaxial films.

The Computer Control Optic Surfacing Polisher Basing on mini industrial robot,with less space and more flexibility. The surface error is figured by the polishing spindle tool, using for optical plane, spherical and aspheric surface. The fitting polishing tool technology basing on the polishing force controller was developed to get the controllable Influence Function and finish the precision optical surface. And High Mark will provide full process solutions from micron to nanometre with the innovative process technology and software.

Based on the principle of Fizeau interference and mechanical phase shifting and equipped with the self-developed super-achromatic beam expanding and imaging system, the interferometer supports the plug and play of laser source with the working wavelength in the range of 600 - 1600 nm.

It provide different polishing and grinding plats with different specs, which could be used in the polishing and grinding of different kinds of optical glasses, quartz, crystals and other fragile flat and sphere surface.
