Q&AQ多层镀膜滤镜比单层镀膜滤镜贵在哪里?A:多层镀膜与单层镀膜一般是在UV滤镜上出现的区别,UV镜的主要功能是用于吸收波长在400毫微米以下的紫外线,适用于海边、山地、雪原和空旷地带等环境下的拍摄,能减弱因紫外线引起的蓝色调,但现在UV镜一般就是用来保护镜头的。多层镀膜的UV镜对成像的影响要比单层镀膜的小很多,它最大的优势就是透光量更高,多层镀膜UV镜的透光量一般都可以达到99%以上,影响可以忽略不计。而单层镀膜的UV就差一
Q & AQ multi-layer coating filter than single-layer coating filter where? A: Multi-layer coating and single coating is generally the difference on the UV filter, UV mirror’s main function is to absorb wavelengths at 400 nm The following UV, for seaside, mountain, snowfields and open areas and other environments shooting, can reduce the UV-induced blue tone, but now UV lens is generally used to protect the lens. Multi-coated UV mirror imaging effect is much smaller than the single-coating, its greatest advantage is the higher light transmission, multi-coating UV mirror transmission capacity can generally be more than 99%, the impact can be ignored Excluding. The single-coating UV difference
