概述：
ARCspectro HT-2D是超紧凑坚固耐用的傅里叶变换光谱仪。基于偏振光学，它提供了极高的灵敏度，是弱光和漫反射测量(漫反射和散射介质)的理想光谱仪，其独特的设计容许大角度收集光。它有几毫米高的入射面，工作原理防止了漂移和暗噪声。由于其2D相机，一次拍摄平均超过1000次测量。可以使用极简单的光学设置，无需聚焦光学系统。
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
应用：
● Diffuse reflection spectroscopy
● Turbid media transmission spectroscopy
● Fluorescence spectroscopy
● Precise peak position (or wavelength determination)
● Colorimet
