光线入射 meaning in English
incidence of light
Examples
- Mica pearlescent pigments comprising mica particles coated with thin transparent film consisting of highly refractive metal oxides , when the light rays incident into pigment particle , a portion of light is reflected from the exterior of the film and interfere with the other portion of light transmitted through the film to the extremely smooth surface of mica plate where it is reflected again . two portion of light suffers a phase change , viewed by reflected light it exhibit pearly or iridescent optical effects , which depending upon the particle size and the thickness of coatings
云母珠光颜料是通过在云母粉表而镀覆一层高折射率的金属氧化物透明薄膜，如tio _ 2 、 fe _ 2o _ 3等，光线入射后，部分光线被膜层表面反射，其余光线穿过膜层照到云母片再被反射，两组反射光线因光程差发生干涉，形成具有彩虹一样的珍珠光泽，被广泛应用于涂料、油墨、塑料、制革、化妆品等行业，能明显改善产品外观，提高产品档次。
