| Zusammenfassung: | The present invention relates to an optical lens comprising a substrate with a front main face and with a rear main face, at least one of the main faces being coated with an antireflection coating, such that in the range [0 DEG-50 DEG] of angles of incidence theta, the mean light reflection factor Rv(theta) on said coated main face presents a minimum value Rvmin for an angle of incidence theta mincomprised in the range [20 DEG-50 DEG], and Rvmin / Rv(15 DEG) < 0.95, Rv(15 DEG) being the mean light reflection factor for an angle of incidence theta of 15 DEG on said coated main face. The optical lens is also useful to inhibit reflection of light in the ultraviolet range.
本发明涉及一种光学镜片，所述光学镜片包括具有前主面和后主面的基材，所述主面中的至少一个主面涂覆有减反射涂层，使得在入射角θ的范围[0°-50°]内，所述有涂层的主面上的平均光反射因数Rv(θ)针对包含在范围[20°-50°]内的入射角θ呈现最小值Rv，并且Rv/Rv(15°) |
