摘要： A coupling optical system for coupling light into an optical fiber of an optical communications system includes a liquid that includes a dispersion of microscopic particles and two transparent media that hold the liquid between them along an optical axis. The refractive power of the liquid is variable according to the electromagnetic field applied to the liquid to vary the migration of the microscopic particles of the dispersion within the liquid. The position of a light collecting point of the coupling optical system is adjustable based on the variation in the refractive power of the liquid so that light can be efficiently coupled into optical fibers at different distances along the optical axis from the coupling optical system. At the light collecting point, the end surface of an optical fiber collects light from a light source or another optical fiber. One or more collimator lenses may help converge the light.

摘要： A high magnification, four-group zoom lens formed of only four lens groups, namely, a first lens group of positive refractive power, a second lens group of negative refractive power, and third and fourth lens groups of positive refractive power. The first lens group includes, in order from the object side, a first lens subgroup that is fixed during focusing and a second lens subgroup that moves during focusing. The second lens group includes, in order from the object side, first and second lens elements having negative refractive power, and first and second doublet components with each formed of a lens element having positive refractive power and a lens element having negative refractive power. To suppress lateral color, specified conditions are satisfied for the Abbe numbers and the refractive indices of the positive refractive power lens elements that are included in the doublet components of the second lens group.
