Design of a multipass optical cell based on the use of shifted corner cubes and right-angle prisms

摘要

A design of a multipass optical cell is proposed. This design is based on the use of corner-cube retroreflectors arranged opposite to parallel axes, an incident beam that enters off the plane that contains the axes of the retroreflectors, and right-angle prisms to return to the cell the beam that left it after several reflections. This design allows the light beam to pass through the cell many times so that the beam paths fill the cell volume tightly and homogeneously. (C) 1998 Optical Society of America. [References: 8]
