Germanium (Ge) Concave Convex Lenses
High-precision concave-convex Germanium (Ge) lenses designed for controlled infrared beam convergence and collimation in MWIR and LWIR imaging, sensing, and laser applications.
Full Product DescriptionProduct description
G&H Concave-Convex Germanium (Ge) lenses are engineered for high-performance infrared (IR) systems operating in the mid-wave and long-wave IR bands (2–14 µm). Featuring one inward (concave) and one outward (convex) curved surface, this design provides refined control of beam divergence or convergence, while minimizing spherical aberration.
Made from high-purity monocrystalline Germanium, these lenses deliver excellent transmission across MWIR and LWIR wavelengths and feature a high refractive index (~4.0 at 10.6 µm). They are commonly used in systems that require improved image fidelity, beam shaping precision, or compact optical packaging.
G&H germanium lenses are available in a variety of custom diameters, focal lengths, and mount options, making them suitable for thermal cameras, IR laser systems, and defense-grade optical assemblies.
