Profile: Global Precision Optics, LLC specializes in custom fabricated optical components for aerospace, defense, medical, commercial and research applications. Our product line includes lenses, mirrors, filters, doublets and magnifiers. Our simple lenses are simple single elements made of glass of fused silica. These lenses come in a variety of forms and shapes having a specific imaging characteristic. These lenses are what make up the beginnings of optical design. Our achromatic lenses doublets are made from two materials of different refractive indicates and dispersions. They provide much better correction of aberrations than a single element.
