概述：
ARCspectro HT-2D是超緊湊堅固耐用的傅里葉變換光譜儀�；谄窆鈱W，它提供了極高的靈敏度，是弱光和漫反射測量(漫反射和散射介質(zhì))的理想光譜儀，其獨特的設(shè)計容許大角度收集光。它有幾毫米高的入射面，工作原理防止了漂移和暗噪聲。由于其2D相機，一次拍攝平均超過1000次測量�？梢允褂脴O簡單的光學設(shè)置，無需聚焦光學系統(tǒng)。
主要特征：
● Ultra High throughput (100x more than a grating spectrometer)
● Large spectral range: 400nm-1100nm
● Very low dark noise 0.02 counts (1024 lines averaging)
● Simple optical setup (no need for extra optics)
● Hardware and software trigger
● No drift
● Very short integration times (0.05ms)
● Variable Gain
● No moving parts
● Metallic anodized housing with useful fixation treads
應(yīng)用：
● Diffuse reflection spectroscopy
● Turbid media transmission spectroscopy
● Fluorescence spectroscopy
● Precise peak position (or wavelength determination)
● Colorimet
