Improved Process Monitoring by Novel Long Pathlength Optical Cell

基于激光的气体分析仪正在成为过程监控行业的首选仪器。基于激光的气体分析仪的性能与测量体积内激光的光路长度直接相关。目前，这一路径长度受到测量单元的光学设计的限制，该光学设计利用球面反射镜在该单元中来回反射光束。该项目将进行一项可行性研究，以展示一种新的分析仪测量单元，使用一种新颖但易于制造的光学设计，与现有设计相比，该设计将使光学路径长度增加一个数量级。这样的电池将为公司提供竞争优势，并为希望利用我们经济、准确和坚固的基于激光的气体分析仪来监控其工艺的客户提供新的机会。

Laser based gas analysers are becoming the instrument of choice in the process monitoring industry. The performance of a laser based gas analyser is directly related to the length of the optical path of the laser beam within the measurement volume. Currently this pathlength is limited by the optical design of the measurement cell which utilises spherical mirrors to reflect the beam back and forth through the cell. This project will undertake a feasibility study to demonstrate a new analyser measurement cell using a novel but easily manufactured optical design which will give an order of magnitude increase in optical pathlength when compared to the existing design. Such a cell will provide the company with a competitive edge and provide new opportunities for customers wishing to utilise our economical, precise and robust laser based gas analysers for monitoring their processes.
