海洋光学NIRQuest近红外光谱仪
| 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，zui高的光学分辨率好于0.25nm（HWHM）。 Thulium Fiber Laser的测量结果
