A coupling interface between a two components of a spectrometer system having a monochromator, a spectrometer and a fiber cable therebetween includes a focusing lens and two crossed cylindrical lenses. The focusing lens is used to assure that the convergence angle of light entering the fiber is within the acceptance angle of the fiber. A dual lens system is used to collimate the light from the monochromator, first in one direction of divergence, then in a second direction of divergence. In a second embodiment, the focusing lens is used to collimate the light from the fiber optic cable. The dual lens system is used to converge the collimated light in two directions.
