Embodiment
As shown in Figure 1 and Figure 2,1 is transparent glass layer, and the material of this glass coating 1 can be simple glass, synthetic glass such as acrylic etc., and its surface can be plane, convex surface or concave surface.At first this glass coating 1 surface is carried out clean and oven dry, plate one deck blooming 2 by the physical vapor deposition (PVD) method at its shady face then.This blooming 2 is a kind of inteferometer coatings of being made up of multilayer specific refractory power difference and the different film of thickness, can present transparent, translucent not even transparence.Owing to form the specific refractory power and the variable thickness sample of every layer film of blooming 2, thus the light intensity and the color that can come the feed glass goods to present at last as required, and and then change and the distinct colors combination to produce the distinct colors effect.In addition, blooming 2 also can be made up of single rete, as the film of titanium oxide series.
For the color that makes glasswork seems bright, full more, the utility model plates one deck reflectance coating 3 on the surface of blooming 2 again by physical gas-phase deposite method.Reflectance coating 3 can be metallic reflective coating, full dielectric medium reflectance coating or inter metal dielectric reflectance coating that both combine.Mostly the metallic reflection mould material is the metallic substance that the spectrum number is big, optical property is more stable, and for example, the metallic reflection mould material commonly used in the ultraviolet region is aluminium, at visible region aluminium commonly used and silver, at infrared region gold and silver commonly used and copper, in addition, chromium and platinum are also often made the coating materials of some extraordinary reflectance coatings.Owing to being easy to oxidation in air, materials such as aluminium, silver, copper reduce performance, so must be protected with dielectric film.Dielectric medium protective membrane material commonly used has silicon monoxide, magnesium fluoride, silicon-dioxide, aluminium sesquioxide etc.
The advantage of metallic reflective coating is that preparation technology is simple, and the wavelength region of work is wide; Shortcoming is that light loss is big, and reflectivity can not be very high.For the reflectivity that makes metallic reflective coating further improves, can add which floor certain thickness dielectric layer of plating in the outside of metallic reflective coating, form the inter metal dielectric reflectance coating.
Full dielectric medium reflectance coating is based upon on the multiple-beam interference basis, and is opposite with anti-reflection film, and full dielectric medium reflectance coating is by being higher than the film of body material to increase the reflectivity of optical surface in optical surface plating one deck specific refractory power.
