NIRQuest新型近红外光谱仪

如果您希望使用近红外光谱技术来做科研、过程控制和诊断，NIRQuest近红外光谱仪是一个低成本，简便的产品。

相比于海洋光学的旧的NIR光谱仪，NIRQuest近红外光谱仪使用了更高性能的光学平台，具有更好的灵敏度和信噪比，同时也有更多的光栅供选择。

NIRQuest近红外光谱仪具有多种版本可供选择，包括NIRQuest512(900－1700nm)，NIRQues256-2.1(900－2050nm)和NIRQuest256-2.5(900-2500nm)。随着新光栅的推出，将有更多的产品供您选择。



使用NIRQuest和新光栅做激光分析

NIRQuest和新的光栅已经完全可以满足在近红外范围内的激光分析使用了，最高的光学分辨率好于0.25nm(HWHM)。
