FT-NIR Rocket近紅外傅立葉變換光纖光譜儀
概述:
近紅外傅里葉變換光譜儀是一個高性能的系統(tǒng)。它具有高分辨、寬的波長范圍和的穩(wěn)定性,其在波長和強(qiáng)度上杰出的穩(wěn)定性使其成為高重復(fù)性化學(xué)計量分析的理想工具。與光電二極管陣列近紅外光譜儀比較,我們的單光電二極管運(yùn)作的傅里葉變換近紅外光譜儀確保無缺陷像素,沒有像素的增益變化,沒有暗電流漂移;而且,這個光譜儀不會遭受到像光柵光譜儀雜散光的影響。
Wide wavelength range 0.9-2.6μm
● High resolution 8cm-1(equivalent to <1nm@1um and <5nm@2.5um)
● Excellent stability in intensity & wavelength scale stability
(no dark current-induced drift, internal reference laser)
● Very good sensitivity (very well adapted for diffuse reflectance)
● Compact and rugger, easy-to-use fiber input system
● Cost effective (single NIR photodiode)
