Recently, miniaturization of Raman, mid-infrared (MIR) and near-infrared (NIR) spectrometers have made substantial progress, and marketing companies predict this segment of instrumentation a significant growth rate within the next few years. This increase will be based on a more frequent implementation for industrial quality and process control and a broader adoption of spectrometers for in-the-field testing, on-site measurements, and every-day-life consumer applications. The reduction in size, however, must not lead to compromises in measurement performance and the hand-held instrumentation will only have a real impact if spectra of comparable quality to laboratory spectrometers can be obtained. The present communication will, on the one hand, explain the instrumental reasons why NIR spectroscopy is presently the most advanced technique regarding miniaturization and on the other hand, it will emphasize the impact of NIR spectroscopy for plant analysis by discussing in some detail a qualitative and a quantitative application example.
最近，拉曼光谱仪、中红外（MIR）光谱仪和近红外（NIR）光谱仪的小型化取得了重大进展，营销公司预测，在未来几年内，这一仪器领域将有显著的增长率。这种增长将基于工业质量和过程控制中更频繁的应用，以及光谱仪在现场测试、现场测量和日常生活消费应用中的更广泛采用。然而，尺寸的减小绝不能导致测量性能的妥协，只有当能够获得与实验室光谱仪质量相当的光谱时，手持式仪器才会产生真正的影响。本通讯一方面将解释为什么近红外光谱目前是小型化方面最先进的技术的仪器原因，另一方面，将通过详细讨论一个定性和一个定量应用实例，强调近红外光谱在植物分析中的影响。
