Germanium infrared aspheric optical lenses are high-performance components designed to focus or collimate infrared light with minimal optical aberrations. Made from germanium, these lenses are ideal for thermal imaging systems and other IR applications due to their high refractive index and excellent transmission in the infrared spectrum, providing superior imaging clarity. CNGEIR offers high-quality infrared aspheric lenses for precise imaging.
