ARCspectro HT-2D超緊湊型高通量傅立葉變換光譜儀

2019/08/07

概述:

ARCspectro HT-2D是超緊湊堅固耐用的傅里葉變換光譜儀。基于偏振光學,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)的理想光譜儀,其獨特的設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。可以使用極簡單的光學設置,無需聚焦光學系統。

 

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

 

應用:

● Diffuse reflection spectroscopy

● Turbid media transmission spectroscopy

● Fluorescence spectroscopy

● Precise peak position (or wavelength determination)

● Colorimet
