                Main Products             Product Description HENGXIANG optical factory produces a wide variety of Germanium Optical Components, including Silte lenses, IR filters, or windows. Germanium optical lenses are ideal for collimation or focusing applications called spent monochromatic light. Each lenses are available in a range of sizes or focal lengths for a wide variety of application needs.   Our Germanium Plano-Convex Lenses feature precision polished surfaces, making them ideal for a variety of infrared applications, including Near-Infrared (NIR) imaging, and infrared spectroscopy. Available in a variety of focal lengths from f/1 thru f/10, the lenses are offered uncoated or broadband anti-reflection coated. For custom infrared coating requirements, please contact our Sales Department.   Applications The notable properties of germania are its high index of refraction and its low optical dispersion. These make it especially useful for wide-angle camera lenses, microscopy, and the core part of optical fibers.  Because germanium is transparent in the infrared wavelengths, it is an important infrared optical material that can be readily cut and polished into lenses and windows. It is especially used as the front optic in thermal imaging cameras working in the 8 to 14 micron range for passive thermal imaging and for hot-spot detection in military, mobile night vision, and fire fighting applications. It is used in infrared spectroscopes and other optical equipment that require extremely sensitive infrared detectors. It has a very high refractive index (4.0) and must be coated with anti-reflection agents.  company introduction Shanghai Hengxiang Optical Electronics Co.,Ltd, located on Shanghai, an international city of China, set up in 2001, is a professional manufacturing high-tech corporation, providesresearch and manufacturing ,entity integrating optical,mechanical and electronic design.
