Germanium lenses are optical lenses fabricated from germanium (Ge) primarily due to its unique optical properties — particularly its high refractive index, thermal stability, and infrared transparency.
Lattice Materials is exceptionally equipped to create optical components, and germanium lenses in particular, to precise optical specifications with any finishing you require.
Our production staff uses precision CNC curve generators to produce best-in-class germanium lenses for any of your requirements — from prototype requests through full production volumes.
Our germanium lenses are used in various high-performance optical systems, particularly in applications that involve infrared imaging systems, remote sensing, and thermal imaging systems.
Optical lenses fabricated from germanium can maintain high optical performance.
Germanium has many advantages, making it a suitable material for fabricating spherical lenses and aspheric lenses for various applications in aerospace, defense, and infrared optics.
