  • Patent number: 4740276
    Abstract: An electroforming method is described for making a cooled segmented aperture (SAM) mirror suitable for use with high energy laser irradiation. The method avoids the problems associated with discrete segment SAMs by using electroforming to fabricate a continuous faceplate having a surface shape of the desired array of segments and coolant channels just below the optical surface to provide improved performance under high energy laser irradiation. A master mirror is fabricated from discrete segments. Raised circular lands on the rear of the segments aid alignment of the segments. A negative faceplate is electroformed on the master mirror. A positive faceplate is electroformed on the negative faceplate. Cooling channels are electrical discharge machined into the back of the positive faceplate and additional material electrodeposited to close the channels.
