Diamond Turned Germanium Lenses
Precision diamond-turned Germanium lenses engineered for high-performance infrared beam shaping, thermal imaging, and laser systems in defense, aerospace, and industrial applications.
Full Product DescriptionProduct description
G&H diamond-turned Germanium lenses offer unmatched precision and performance in mid-wave and long-wave infrared (MWIR and LWIR) optical systems. These lenses are machined using state-of-the-art single-point diamond turning (SPDT) technology to produce aspheric, freeform, or diffractive surfaces with nanometric accuracy.
Crafted from high-purity monocrystalline Germanium, these lenses exhibit excellent IR transmission from 2 to 14 µm and support complex optical designs that reduce aberrations and system size. Ideal for use in thermal imaging, IR laser beam shaping, and multi-spectral sensing, diamond-turned lenses enable next-generation performance in compact, rugged optical systems.
G&H offers custom configurations with optional broadband anti-reflective (AR) or diamond-like carbon (DLC) coatings to enhance transmission and environmental resistance.
