概述：
FT-NIR Rocket近红外傅里叶变换光谱仪是一个高性能的系统。它具有高分辨、宽的波长范围和极好的稳定性，其在波长和强度上杰出的稳定性使其成为高重复性化学计量分析的理想工具。与光电二极管阵列近红外光谱仪比较，我们的单光电二极管运作的傅里叶变换近红外光谱仪确保无缺陷像素，没有像素的增益变化，没有暗电流漂移；而且，这个光谱仪不会遭受到像光栅光谱仪杂散光的影响。
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)
