Abstract
A method of making an array of vapor cells for an array of magnetometers includes providing a plurality of separate vapor cell elements, each vapor cell element including at least one vapor cell; arranging the vapor cell elements in an alignment jig to produce a selected arrangement of the vapor cells; attaching at least one alignment-maintaining film onto the vapor cell elements in the alignment jig; transferring the vapor cells elements and the at least one alignment-maintaining film from the alignment jig to a mold; injecting a bonding material into the mold and between the vapor cell elements to bond the vapor cell elements in the selected arrangement; removing the at least one alignment maintaining film from the vapor cell elements; and removing the bonded vapor cells elements in the selected arrangement from the mold to provide the array of vapor.
