HCVAC vacuum optical coating machine is applied to lens, lens, vehicle, digital camera, smart phone, projector, filter and other industries. It is specially designed for the production of optical film products with few layers but high production capacity and high efficiency. The antireflection film can reduce the surface reflected light of lens and increase the transmission light. When there are many lenses, they must be low reflection. In addition to multilayer films, double-layer films with specific wavelengths are also used on MgF2 monolayer and laser head, which can be coated on plastic products at low temperature.
