Product Overview
The germanium aspheric lens is an aspheric lens made from germanium (Ge) as the base material. Germanium is known for its high transmittance, chemical inertness, and excellent thermal conductivity, making it particularly suitable for infrared optical systems. Germanium is widely used in the mid-to-long wave infrared region due to its good transmission performance. The germanium aspheric lens is precisely designed to correct the aberrations present in traditional spherical lenses, enhancing image quality, and optimizing the direction and focus of light propagation.
Compared to traditional spherical lenses, germanium aspheric lenses offer superior optical performance, reducing light scattering and reflection while increasing light transmission strength and clarity. Furthermore, germanium aspheric lenses can be customized to meet the specific requirements of different optical systems.
