SBIR Phase II: High Sensitivity Raman Spectrometer

这个小型企业创新研究（SBIR）第二阶段项目将设计、构建和测试一个适合“按需”或连续过程监控的混合拉曼分析仪。第一阶段项目通过设计和测试一种独特的组件组合来证明可行性，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。该新型设计还具有高分辨率（1 cm -1）、恒定波长稳定性和不受荧光干扰的特性；这是自主化学过程监控或快速原料识别的关键要求。二期工程将进一步提高灵敏度，并表现出长期的温度和振动抗扰性，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，该分析仪将坚固耐用，紧凑便携（10“x 12”占地面积），维护成本低，功耗最低，适用于众多工业应用。商业应用将直接针对化学制造业。第二阶段的原型将在第三阶段与客户一起开发特定的应用。

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.
