超高靈敏度微型光譜儀的特點：此款光譜儀為*設計的，單光子響應級別的超高靈敏度微型光譜儀，由于其采用偏振光學設計，不同于傳統的光柵式光譜儀，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量的理想選擇，可用于熒光光譜，漫反射光譜，拉曼光譜分析。
900-1700nm （HT-NIR） < 10 nm @ l = 1000 nm （HT-NIR model） InGaAs 512 pixels （HT-NIR） 1 stage cooled
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）.
