Abstract:

To develop a multi-pass gas cell with maximum pathlength and minimum volume employing On-Lines patented non-spherical, aberration-correcting optics. Ray tracing analysis for the proposed small volume, long optical pathlength gas cell was completed. The analysis has resulted in a design which meets the 500 cc gas volume constraint for the cell, while preserving the optical image quality over a suitably long pathlength. The analysis has indicated that a 50 meter effective pathlength is possible within the small volume constraint. To design, purchase and implement the infrared transfer optics to couple the miniature gas cell to a contractor owned FT-IR spectrometer suitable for on-site use. The Phase I monitor will be demonstrated for measurement sensitivity and speed during TCE monitoring. To evaluate the degree to which the overall Phase I objective was met and to formulate a preliminary design for a Phase II prototype. p1,6,8
