Array collimator structure

The utility model relates to the field of laser communication, in particular to a collimator device for optical fiber communication. An array collimator structure comprises an array optical fiber head, a longitudinal array lens assembly and a transverse array lens assembly which are arranged on an optical path sequentially, wherein a plurality of optical fibers are arranged on the array optical fiber head in an array; N longitudinally-distributed array cylindrical lenses corresponding to the positions of the longitudinally-distributed optical fibers are arranged on the longitudinal array lens assembly; M transversely-distribbuted array cylindrical lenses corresponding to the positions of the transversely-distributed optical fibers are arranged on the transverse array lens assembly; the array optical fiber head is arranged at the position of a focus f1 of the longitudinal array lens assembly; and the longitudinal array lens assembly is arranged at the position of a focus f2 of the transverse array lens assembl
