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(tǒng)。它具有高分辨、寬的波長(zhǎng)范圍和極好的穩(wěn)定性，其在波長(zhǎng)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(jì)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(wú)缺陷像素，沒有像素的增益變化，沒有暗電流漂移；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。
主要特征：
● 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)
