Gonio-spectrophotometers变角分光光度仪
许多行业，包括化妆品和汽车行业，都对珠光和金属等特殊效果非常感兴趣。这些颜料使颜料在不同的角度看起来不同。我们都见过根据你站的位置或金属板的角度而改变颜色的汽车。
变角分光光度计Gonio-spectrophotometers是第一个可以像我们一样看到颜色变化的多角度装置，但是它们非常大，而且非常昂贵。今天，我们有便携式多角度测色仪，可以从多个角度测量表面。它们使用一个照明点（通常为45度）和多个不同的接收器来捕捉和记录光线在不同方向上的散射。
除汽车工业外，这些仪器还用于指甲油和眼妆的化妆品，以及其他生产具有有趣光学特性的材料的行业。
Many industries, including cosmetics and automotives, are very interested in special effects like pearlescents and metallics. These pigments make the paint look different at different angles. We’ve all seen cars that appear to change colors depending on where you’re standing or the angle of the sheet metal.
Gonio-spectrophotometers were the first multi-angle devices that could see color shifts the way we do, but they were very big, and very expensive. Today we have portable, handheld, multi-angle instruments that can measure a surface from many angles. They work with a single point of illumination, typically at 45 degrees, and a number of different receivers that capture and record the light as it scatters in different directions.
In addition to the auto industry, these instruments are used in cosmetics for fingernail polish and eye makeup, and other industries that produce materials with interesting optical properties.
