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).
