Special Shaped Germanium Lens
Description
Special shaped Germanium lens is an optical lens made using germanium (Ge) as a material with a high refractive index and a wide spectral operating range (2-16μm). It typically has a small surface curvature and chromatic aberration, which helps maintain image clarity and sharpness in imaging systems. It has excellent chemical stability and mechanical properties to maintain high performance in harsh environments.
