SBIR Phase II: High Sensitivity Raman Spectrometer

该小型企业创新研究（SBIR）第二阶段项目将设计、制造和测试一种适合“按需”或连续过程监测的混合拉曼分析仪。 第一阶段项目通过设计和测试独特的组件组合证明了可行性，与传统的拉曼分析仪相比，该组件的灵敏度（定义为信噪比）提高了100倍以上。新的设计还表现出高分辨率（1 cm-1），不变的波长稳定性，并从荧光干扰的自由，这是自主化学过程监测或快速原材料识别的关键要求。 第二阶段项目将进一步提高灵敏度，并展示长期的温度和振动免疫力，以及快速的“开启”时间。 完整的内部分析仪诊断将允许超过1000小时的无人值守操作。 因此，该分析仪将是坚固的，紧凑的和便携式的（10“x 12”的足迹），低维护，需要最小的功率，并适用于许多工业应用。商业应用将面向化学制造业。第二阶段原型将用于在第三阶段与客户一起开发特定应用程序。

This Small Business Innovation Research (SBIR) Phase II project will design, build, and test a hybrid Raman analyzer suitable for "on-demand" or continuous process monitoring. The Phase I project demonstrated feasibility by designing and testing a unique combination of components that yielded greater than 100 times improvement in sensitivity (defined as the signal-to-noise ratio) compared to traditional Raman analyzers. The novel design also demonstrated high resolution (1 cm -1), invariant wavelength stability, and freedom from fluorescence interference; which are critical requirements for autonomous chemical process monitoring or rapid raw-material identification. The Phase II project will further improve sensitivity, as well as demonstrate long-term temperature and vibrational immunity, and fast "turn-on" time. Complete internal analyzer diagnostics will allow greater than 1000 hours of unattended operation. As such, the analyzer will be rugged, compact and portable (10"x 12" footprint), low-maintenance, require minimum power, and suitable for numerous industrial applications. The commercial applications will be directed toward the chemical manufacturing industries. The Phase II prototype will be used to develop specific applications with customers during Phase III.
