This photograph shows Wes Brown, Marshall Space Flight Center's (MSFC's) lead diamond tuner, an expert in the science of using diamond-tipped tools to cut metal, inspecting the mold's physical characteristics to ensure the uniformity of its more than 6,000 grooves. This king-size copper disk, manufactured at the Space Optics Manufacturing and Technology Center (SOMTC) at MSFC, is a special mold for making high resolution monitor screens. This master mold will be used to make several other molds, each capable of forming hundreds of screens that have a type of lens called a fresnel lens. Weighing much less than conventional optics, fresnel lenses have multiple concentric grooves, each formed to a precise angle, that together create the curvature needed to focus and project images. The MSFC leads NASA's space optics manufacturing technology development as a technology leader for diamond turning. The machine used to manufacture this mold is among many one-of-a-kind pieces of equipment of MSFC's SOMTC.
