概述：
ARCspectro HT-HR是一個(gè)基于偏振光學(xué)，堅(jiān)固耐用的傅里葉變換光譜儀。它提供了極高的靈敏度，是弱光和漫反射測(cè)量的理想光譜儀，其獨(dú)特的設(shè)計(jì)容許在幾毫米大的表面收集光。這比光柵光譜儀(有類似分辨率的)收集的光要多50倍。這個(gè)光收集過程是極為簡單的，只要把待分析的光照射在4毫米入射窗口上即可，無需復(fù)雜和昂貴的聚焦光學(xué)系統(tǒng)。ARCspectro HT-HR也能夠與大光導(dǎo)結(jié)合使用(見右圖)。
主要特征：

● Large spectral range: 400nm-1050nm
● High resolution
● No moving parts, Robust monolithic design
應(yīng)用：
