ARCspectro HT-HR超高通量傅立葉變換光譜儀
Light can be brought to the spectrometervia a 4mm diameter light guide
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。它提供了的靈敏度，是弱光和漫反射測(cè)量的理想光譜儀，其的設(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(guò)程是極為簡(jiǎn)單的，只要把待分析的光照射在4毫米入射窗口上即可，無(wú)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)。
