Abstract
An optical component formed of a material that blocks noise-causing visible and near-infrared rays selectively or as a whole while transmitting far-infrared rays to the extent possible, and a method for producing the component. The component is produced by adding at least one additive that blocks visible and near-infrared rays to a ceramic material of ZnS, ZnSe, or Ge. The component is most suitable for a particular purpose or use of an optical component, such as a window or lens to be used in a high-performance infrared apparatus, because noise-causing visible and near-infrared rays are blocked.
