FT-NIR Rocket近紅外傅立葉變換光纖光譜儀
2019/08/07
概述：
FT-NIR Rocket近紅外傅里葉變換光譜儀是一個(gè)高性能的系統。它具有高分辨、寬的波長(cháng)范圍和極好的穩定性，其在波長(cháng)和強度上杰出的穩定性使其成為高重復性化學(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作的傅里葉變換近紅外光譜儀確保無(wú)缺陷像素，沒(méi)有像素的增益變化，沒(méi)有暗電流漂移；而且，這個(gè)光譜儀不會(huì )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 <[email protected])
● 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)
