  光谱仪只是一个光谱采集的模块,任何光谱应用的解决方案,如果没有配套的光源,采样部件是无法工作的。20多年来业界在满足成千上万个光谱应用的过程中,发展了各种配套的微型光源模块,数以千计的包括探头,光纤,比色皿,采样部件,操作App。一定不要低估它们在拓展微型光谱仪应用方面的作用。

  The spectrometer is only a spectral acquisition module for any spectral application solution, if there is no matching light source, the sampling part is not working. Over the past 20 years, the industry has been able to meet the needs of tens of thousands of spectrum applications, the development of a variety of supporting micro light source modules, including thousands of probes, optical fiber, cuvette, sampling components, operating software. Do not underestimate their role in the development of micro spectrometer applications.
