More Information
Summary:The invention discloses a vacuum coating camera cover plate and a preparation method thereof. The cover plate is characterized by comprising a substrate (1), wherein the upper surface and the lower surface of the substrate (1) are sequentially coated with a 28-50nm thick trititanium pentoxide layer (2) and a 105-150nm thick silicon dioxide layer (3); and the thickness of the substrate is 0.4-0.6mm. The cover plate has the advantages of uniform coating, high transmittance and abrasion resistance.
