Description

Technical Field

[0001] The utility model belongs to the technical field of coated glass, and in particular relates to an anti-reflection coated glass. Background Art

[0002] Anti-reflective coated glass is made by coating the surface of high-quality glass with an anti-reflective film using methods such as physical vapor deposition, chemical vapor deposition, and chemical sol coating, so that the reflected light generated by the front and back surfaces of the film layer interferes with each other, thereby offsetting the reflected light and enhancing the transmitted light, making the glass surface have low reflection and high transmission properties. This can eliminate the glare problem of the glass and make the scenery clearer, so it is widely used in window glass, picture frame glass, display cabinet glass, etc. in street shops.

[0003] At present, the anti-reflection coated glass used in jewelry display cabinets can only meet the function of eliminating glare and making the jewelry clearer. There is no anti-reflection coated glass that can show the radiant charm of the unique high refraction of jewelry. Therefore, it is necessary to develop an anti-reflection coated glass that is more suitable for use in jewelry display cabinets. Utility Model Content

The glass plate comprises a first surface and a second surface opposite to each other. The first coating film layer is arranged on the first surface, and the second coating film layer is arranged on the second surface.

[0007] The first coating film layer includes a first film layer and a second film layer stacked sequentially from the first surface to the outside, and the second coating film layer includes a third film layer and a fourth film layer stacked sequentially from the second surface to the outside.

[0008] The materials of the first film layer and the third film layer are both Si3N4, and the materials of the second film layer and the fourth film layer are both SiO2.

[0009] The thickness of the first film layer is 28.4±1 nm, the thickness of the second film layer is 122.5±2 nm, the thickness of the third film layer is 28.4±1 nm, and the thickness of the fourth film layer is 122.5±2 nm.

[0011] Further, the thickness of the first film layer is 28.4 nm, the thickness of the second film layer is 122.5 nm, the thickness of the third film layer is 28.4 nm, and the thickness of the fourth film layer is 122.5 nm.

[0012] Furthermore, the reflectivity of the glass plate to light incident at an incident angle of 8° is less than or equal to 9%.

[0013] Furthermore, the transmittance of the glass plate to light incident at an incident angle of 8° is greater than or equal to 89%.

[0014] Compared with the prior art, the beneficial technical effects of the utility model are:

[0015] The utility model is not only an anti-reflection glass, but also reflects the color of the point light source in purple-red under light. When used in a jewelry display cabinet, it can not only enable consumers to clearly see the brilliant light of the jewelry, but also the purple-red light spot formed by the point light source also reflects the light of the jewelry, showing the radiant charm of the jewelry's unique high refraction.
