ABSTRACT OF THE DISCLOSURE A fiber optic connector in the form of a two-element relay system which transforms and matches the numerical apertures of an entering beam to that of the acceptance numerical aperture of the exiting optic where in general the numerical apertures can be dif- ferent. In preferred form, the connector is a pair of spherical balls with their surfaces in contact at a point along an optical axis extending through the centers of the balls. The radii of the spherical balls and their material composition are such that they operate to image fibers or the like one onto the other with their numeri- cal apertures matched when each of the fibers are in optical contact with a respective one of the spherical balls at a point along the optical axis opposite the point of contact. The radii and indices of refraction of the spherical balls can be adjusted to assure that optics with different numerical apertures are optimally coupled. Means are included for maintaining the spheri- cal balls in contact while permitting connector adjust- ment for optimizing throughput.
