超高感度マイクロ分光計の特徴:この分光計は独特に設計され、単一光子応答レベルの超高感度マイクロ分光計偏光光学設計を採用しているため、従来の格子式分光計とは異なり、スリットを必要とせず、光ファイバを使用せず、大きな受光面積を持たせることができる。したがって、この金超高感度分光計低光照射測定のための理想的な選択であり、蛍光スペクトル、拡散反射スペクトル、ラマン分光分析。
ARCspectro HT is ideal for low light applications or for the spectral analysis of diffusing light sources (or samples). Its unique design permits togather a maximum of lightover a large diffusing surface (several millimeters!) and over a large angle (±10°). This gives atremendous 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).
