Abstract
The utility model discloses a kind of sapphire window sheet, include the substrate that sapphire is made, be coated with antireflection film coating in the one side of substrate; The another side of described substrate is coated with antireflection anti scuffing film coating; Anti-dirty trace film coating is coated with outside described antireflection anti scuffing film coating.The number of plies of described antireflection film coating is 6 layers, and the thickness of antireflection film coating is 235nm.The number of plies of described antireflection anti scuffing film coating is 6 layers, and the thickness of antireflection anti scuffing film coating is 250nm.The number of plies of described anti-dirty trace film coating is 1 layer, and the thickness of anti-dirty trace film coating is 20nm.Sapphire window sheet described in the utility model prevents the effective of dirty, dust, trace, and have extremely strong scratch resistance effect, light penetration is high, not only increases serviceable life, also improves the sharpness of its imaging, stable and reliable for performance, Practical Performance is strong.
Description
Technical field
The utility model belongs to mobile phone camera protective lens technical field, especially relates to a kind of sapphire window sheet.
Background technology
Mobile phone camera protective lens can prevent mobile phone camera from coming to harm.Protective lens is fixed on mobile phone usually, more difficult replacing, therefore how to improve the performance outbalance such as anti-wear, anti-dirty of protective lens itself.
Existing mobile phone camera protective lens is glass window sheet, and its surface becomes easily infected by dirty, dust and trace, and dirty, the grieshoch be stained with and trace are not easily wiped free of.The skin hardness of glass window sheet is low, easily scratches, and causes irreversible injury.And its light penetration is also lower, T ≈ 91.5%, causes imaging unintelligible.Above-mentioned defect all can affect the photographic effect of mobile phone.
Utility model content
The purpose of this utility model to solve the deficiencies in the prior art part, and provide a kind of sapphire window sheet preventing dirty, dust and trace, and its skin hardness is high, and light penetration is high, substantially increases the sharpness of mobile phone camera imaging.
The purpose of this utility model is solved by following technical proposal:
A kind of sapphire window sheet, is characterized in that: include the substrate that sapphire is made, is coated with antireflection film coating in the one side of substrate; The another side of described substrate is coated with antireflection anti scuffing film coating; Anti-dirty trace film coating is coated with outside described antireflection anti scuffing film coating.
Preferably, the number of plies of antireflection film coating described in the utility model is 6 layers, and the thickness of antireflection film coating is 235nm.
Preferably, the number of plies of antireflection anti scuffing film coating described in the utility model is 6 layers, and the thickness of antireflection anti scuffing film coating is 250nm.
Preferably, the number of plies of anti-dirty trace film coating described in the utility model is 1 layer, and the thickness of anti-dirty trace film coating is 20nm.
Compared to the prior art the utility model has following characteristics and beneficial effect:
1, fingerprint, booty or trace is not easily produced, if when having dust, booty, trace to appear at surface, be also easier to by wiped clean during operation.
2, sapphire window sheet has extremely strong scratch resistance effect, and Mohs value is up to 9H.
3, improve light penetration, its transmitance T >=98%, enhances brightness, and imaging is more clear.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation one.
Fig. 2 is the utility model structural representation two.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
See Fig. 1, Fig. 2, substrate 1 of the present utility model is the substrate 1 be made up of sapphire, is coated with antireflection film coating 2 in the one side of substrate 1.The another side of described substrate 1 is coated with antireflection anti scuffing film coating 3.Anti-dirty trace film coating 4 is coated with outside described antireflection anti scuffing film coating 3.
Preferably, the number of plies of antireflection film coating 2 described in the utility model is 6 layers, and the thickness of antireflection film coating 2 is 235nm.
Preferably, the number of plies of antireflection anti scuffing film coating 3 described in the utility model is 6 layers, and the thickness of antireflection anti scuffing film coating 3 is 250nm.
Preferably, the number of plies of anti-dirty trace film coating 4 described in the utility model is 1 layer, and the thickness of anti-dirty trace film coating 4 is 20nm.
Using sapphire as substrate 1, and at its surface coverage antireflection film coating 2, antireflection anti scuffing film coating 3 and anti-dirty trace film coating 4.During operation, sapphire window sheet surface not easily produces fingerprint trace, is also not easy to be infected with dirty and dust, if when having dust, booty, trace to appear at surface, be also easier to by wiped clean.Sapphire window sheet skin hardness is high, and Mohs value, up to 9H, has extremely strong scratch resistance effect, adds its serviceable life.Meanwhile, sapphire window sheet is compared to common glass window sheet, and its light penetration improves greatly, and transmitance T >=98% enhances brightness, and imaging is more clear.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Claims (4)
