Esco Optics is a US based, ITAR regisitered manufacturer of precision optics. Founded in 1955 Esco creates custom and catalog optics in any shape or configurations. We see ourselves as a hybrid manufacturer, accomplished to handle large manufacturing, but also nimble to take on single and short run fabricated prototypes. We work with the full spectrum of optical materials; Fused Silica, Fused Quartz, BK-7, Zerodur, Sapphire, Germanium, Silicon and Zinc Selenide. Our most common components are optical blanks, windows, witness samples, filters, prisms, laboratory supplies, lenses-aspheres, achromats, acylinders, bi-convex and plano-convex.
