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。它具有高分辨、寬的波長范圍和的穩定性，其在波長和強度上杰出的穩定性使其成為高重復性化學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)
