Lens

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.

Crystro supplies highend Nd:YAG .Neodymium-doped yttrium aluminum garnet (Nd:YAG) is the earliest and most famous and widely used laser crystal.Because of its many excellent basic properties, Nd:YAG is still often used in near-far infrared solid-state lasers and their frequency doubling and frequency doubling.

CO2 cosmetic lens is mainly applied in the field of cosmetic plastic surgery. Its substrate is silicon/K9.

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.

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