瑞士Arcoptix VIS-NIR DR可見-紅外光漫反射分光儀是為在整個可見和近紅外光譜范圍測量樣品的漫反射而設(shè)計的實驗室光譜儀。
ARCspectro VIS-NIR DR可見-近紅外傅立葉變換光譜儀是把一個標(biāo)準(zhǔn)的多通道光柵光譜儀(覆蓋可見光譜范圍:360nm-950nm)和一個掃描傅里葉變換光譜儀(FTIR-Rocket)結(jié)合在一起,掃描傅里葉變換光譜儀具有近紅外900nm-2600nm靈敏擴展的InGaAs探測器。兩個光譜儀連接到一個5cm的積分球。樣品用***的漫反射光照射,由于積分球含有高功率鹵素?zé)簟?/span>
ARCspectro VIS-NIR DR容許在整個太陽光譜范圍獲得全反射。,太陽輻射能量的一半位于近紅外光譜區(qū),對于覆蓋360nm到2500nm整個太陽發(fā)射范圍(在地球上)的許多應(yīng)用(涂料、塑料和化妝品)是非常重要的。
現(xiàn)在市場上的大多數(shù)產(chǎn)品只提供可見區(qū)360-800nm的反射表征,市場上覆蓋這個光譜范圍的產(chǎn)品是價格昂貴、緩慢且體積龐大的單色儀。
ARCspectro VIS-NIR DR按要求也提供透射測量產(chǎn)品,我們也有光纖版的VIS-NIR光譜儀。
