Shanghai LaserMa Crystals, Inc. supplies MgO Magnesium Oxide single crystal substrates, ingots, and optical components.
Shanghai LaserMa Crystals, Inc. supplies MgO single crystal substrate products which are widely used for HTSC (high temperature superconductor) thin film coatings.
MgO single crystal is with high transparency in the wide spectra range from UV to IR.
MgO single crystal is also adopted in the epitaxial area, as well as the deposition of ferroelectric thin film coatings and plasma display panel (PDP) technology. MgO single crystal is ‘epi-ready’ available by one side or two sides polished. The standard thickness of the ‘plates’ or wafers is 0.5 mm. Shanghai LaserMa Crystals Inc. can supply the high quality MgO single crystal upon the requests of customers.
