Germanium Ge infrared optical windows and wafers
Valley Design is a manufacturer of infrared optical materials. Our products are derived from germanium crystals and become optoelectronic materials for infrared optics, night vision, laser applications, and x-rays. We have the capability of manufacturing an ultra-thin germanium wafer (25 microns), as well as exceptional quality infrared optical wafers. Valley Design’s germanium optical window has a broad transmission range and is well suited for infrared applications. We offer a large variety of our infrared optical wafer, including stainless steel, sapphire, silicon, and bonded wafers to name a few.
We strive to have excellent service regarding flatness, parallelism, tolerances, and surface finish for all our products.
