title: Multiple traversal absorption cell of minimum volume: design.
abstract: The design oThe author is with General Electric Company, Valley Forge Space Center, P.O. Box 8555, Philadelphia, Pennsylvania 19101.f a three-mirror absorption cell, first described by White and later improved on by Bernstein and Hertzberg, was analyzed by Edwards to be a unique optical configuration where the only aberration of consequence is astigmatism and associated image curvature. Edwards derived a formula whereby the astigmatic image length could be calculated. This paper relates cell design parameters in a manner that will attain the smallest volume consistent with the design objectives of the objective optics that precede the cell.
