Abstract
A multiple pass optical cell and method comprising providing a pair of opposed cylindrical mirrors having curved axes with substantially equal focal lengths, positioning an entrance hole for introducing light into the cell and an exit hole for extracting light from the cell, wherein the entrance hole and exit hole are coextensive or non-coextensive, introducing light into the cell through the entrance hole, and extracting light from the cell through the exit hole.

A multiple pass optical cell comprising a pair of opposed cylindrical mirrors having curved axes with substantially equal focal lengths, an entrance hole for introducing light into the cell, and an exit hole for extracting light from the cell, wherein said entrance hole and exit hole are coextensive or non-coextensive.
A multiple pass optical cell comprising a pair of opposed cylindrical mirrors having curved axes crossed at angles other than approximately 0, 90, 180, and 270 degrees, an entrance hole for introducing light into the cell, and an exit hole for extracting light from the cell, wherein said entrance hole and exit hole are coextensive or non-coextensive.
A multiple pass optical cell method comprising the steps of:
- providing a pair of opposed cylindrical mirrors having curved axes with substantially equal focal lengths;
- positioning an entrance hole for introducing light into the cell and an exit hole for extracting light from the cell, wherein the entrance hole and exit hole are coextensive or non-coextensive;
- introducing light into the cell through the entrance hole;
- and
- extracting light from the cell through the exit hole.
