FT-NIRRocket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(gè)高性能的系統(tǒng)

詳細(xì)介紹

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(gè)高性能的系統(tǒng)。它具有高分辨、寬的波長(zhǎng)范圍和的穩(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(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 <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)
