Double-Pendulum Grinding and Polishing Machine

Base on phase-shifting technique, the laser interferometer, widely used in the high-precision measurement of planar and spherical optical components, characterizes the three-dimensional topography of the measured surface with a precision of 0.06 μm (Peak-to-valley) or higher.

Ion Beam Figure Machine Tool is working by high beam density, small beam divergence angle and large beam uniformity High energy ion beam bombards the surface of optics, to achieve ultra-precision surface error. The generation of high-energy ions is based on high purity inert gas, passing through hollow cathode. The electrode generates ionization under the discharge of the power module and injects the electron beam into the cavity, and the electron beam is uniformly distributed into the anode area through the electron uniform plate under the action of the electric field and magnetic field of the anode. the electric field of the grid The output ion beam is controlled by the system to achieve uniform and stable surface removal of optical elements.

Crystro supplies TSAG-grade TGG. TGG is an excellent magneto-optical crystal material, which is used in all kinds of Faraday isolators and rotators. The applicable wavelength is 400nm-1100nm (except 475-500nm). Products certified by international customers (https://www.en.crystro.cn/the-role-of-luagce-scintillator-crystals-in-radiation-detection-2/).

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.
