超高靈敏度微型光譜儀的特點(diǎn)：此款光譜儀為設(shè)計(jì)的，單光子響應(yīng)級(jí)別的超高靈敏度微型光譜儀，由于其采用偏振光學(xué)設(shè)計(jì)，不同于傳統(tǒng)的光柵式光譜儀，不需要狹縫，也可不用光纖，使其具有超大的受光面積。因而，此款超高靈敏度光譜儀是用于低光照測(cè)量的理想選擇，可用于熒光光譜，漫反射光譜，拉曼光譜分析。
ARCspectro HT is ideal for low light applications or for the spectral analysis of diffusing light sources (or samples). Its unique design permits to gather a maximum of light over a large diffusing surface (several millimeters!) and over a large angle (±10°). This gives a tremendous throughput advantage (~50x more) compared to the most powerful grating spectrometers (also well-known Jaquinot advantage) which are intrinsically limited by a small entrance slit (typically 0.025mm). This makes this unique device ideal for applications were small light intensities has to be analyzed (fluorescence or Raman spectroscopy).
