Wilson Analytical is an Edmonton-based manufacturer of optical instrumentation, with a particular focus on rugged field-deployable fluorescence, absorption, and Raman spectroscopy instruments for the life-sciences, energy, agriculture, and educational applications, amongst others.The company has identified a set of challenges related to their 'Raman One' instrument:i. The instrument employs high-power, spatially multi-modal lasers, which creates challenges with respect to efficient delivery and focusing of this pump light at the sample plane. There is a need to optimize the optical path between the light source and the sample.ii. The instrument employs a miniature transmission-grating based spectrometer engine, and there is a need to optimize the optical path between the sample and the spectrometer engine.Wilson also markets a suite of 'Lightbox' instruments, which are stabilized, high brightness light sources. Currently, these instruments output a free-space beam. However, the company has identified a need to offer fiber-optic-coupled versions of these light sources, and the proposed work will also address challenges related to this need.Working closely with Wilson Analytical engineers and chemists, the university researchers will apply their extensive experience in fiber and free-space optics to these real-world challenges, and will deliver an improved design of the optical interfaces through the use of appropriate lenses, fibers, or mirrors. The resulting improved instruments will offer greater flexibility for delivery of pump light to liquid and solid samples, while maintaining the key advantages of the instruments already marketed by Wilson Analytical (e.g. rugged construction, portability, and low cost).We anticipate that this project will yield significantly improved instruments, thereby enhancing the competitive position of the industrial partner.

Wilson Analytical是一家位于埃德蒙顿的光学仪器制造商，特别专注于坚固的现场可部署荧光，吸收和拉曼光谱仪器，用于生命科学，能源，农业和教育应用等。该公司已经确定了与他们的“拉曼一号”仪器相关的一系列挑战：该仪器采用高功率、空间多模态激光器，这给泵浦光在样品平面上的有效传递和聚焦带来了挑战。需要优化光源与样品之间的光路。该仪器采用微型透射光栅光谱仪引擎，需要对样品与光谱仪引擎之间的光路进行优化。威尔逊还销售一套“灯箱”仪器，这是稳定的，高亮度光源。目前，这些仪器输出的是自由空间光束。然而，该公司已经确定需要提供这些光源的光纤耦合版本，并且拟议的工作也将解决与此需求相关的挑战。该大学的研究人员将与威尔逊分析工程师和化学家密切合作，将他们在光纤和自由空间光学方面的丰富经验应用于这些现实世界的挑战，并将通过使用适当的透镜、光纤或反射镜来改进光学接口的设计。由此产生的改进仪器将为泵光输送到液体和固体样品提供更大的灵活性，同时保持威尔逊分析公司已经销售的仪器的主要优势（例如坚固的结构，便携性和低成本）。我们预计该项目将大大改进仪器，从而提高工业伙伴的竞争地位。
