多波段防护镜光学薄膜的研制

紫外、蓝光、近红外等波段的光对人眼有一定程度的危害,这些波段的光存在于各种光电系统中,使用者需要佩戴防护镜进行防护.为了能够同时实现对上述三个波段的防护,通过膜系设计软件设计了防护膜系和增透膜系,采用电子束蒸发的方式进行了镀制,以电阻蒸发的方式在镜片两侧加镀了防水膜,并对镜片的光谱性能和防水性能进行了测试.结果 表明,...

Preparation of Optical Film for Multi-band Protective Glasses

Light in the ultraviolet,blue,and nearinfrared bands is harmful to human eyes to a certain extent.Light in these bands exists in various photoelectric systems,and users need to wear protective glasses for protection.In order to achieve the protection of the above three bands at the same time,the protective and the antireflection film systems are designed through the film system design software,which is deposited by electron beam evaporation.The waterproof film is deposited on both sides of the lens by resistance evaporation.And the spectral and waterproof performances of the lens are tested.Testing results show that the developed coated lenses have an average transmittance of about 0.5%,38%,96%and 40%in the ultraviolet band of 250~360 nm,the blue band of 400~430 nm,the visible band of 500~780 nm and the near infrared band of 900?1400 nm,respectively.The water drop angle can reach 113°,which can effectively reduce the damage of ultraviolet,blue and near infrared to human eyes,and the lens has low color cast,high visible light transmittance and good waterproof effect.
