ARCspectro VIS-NIR是为在整个可见和近红外光谱范围测量样品的漫反射而设计的实验室光谱仪。
ARCspectro VIS-NIR可见-近红外傅立叶变换光谱仪是把一个标准的多通道光栅光谱仪(覆盖可见光谱范围：360nm-950nm)和一个扫描傅里叶变换光谱仪(FTIR-Rocket)结合在一起，扫描傅里叶变换光谱仪具有近红外900nm-2600nm灵敏扩展的InGaAs探测器。两个光谱仪连接到一个5cm的积分球。样品用完美的漫反射光照射，由于积分球含有高功率卤素灯。
ARCspectro VIS-NIR容许在整个太阳光谱范围获得全反射。众所周知，太阳辐射能量的一半位于近红外光谱区，对于覆盖360nm到2500nm整个太阳发射范围(在地球上)的许多应用(涂料、塑料和化妆品)是非常重要的。
现在市场上的大多数产品只提供可见区360-800nm的反射表征，市场上唯一覆盖这个光谱范围的产品是价格昂贵、缓慢且体积庞大的单色仪。
ARCspectro VIS-NIR按要求也提供透射测量产品。我们也有光纤版的VIS-NIR光谱仪。
