Germanium’s unique properties are attributed to its high density, which imparts remarkable ruggedness to the lenses, making them ideal for challenging conditions. Its ability to transmit infrared light efficiently, especially in the 2-12 μm band, highlights its suitability for thermal imaging applications and other IR-sensitive tasks.

When it comes to focal lengths, our spherical plano-convex, concave-convex, and aspheric germanium lenses offer precise control, with tolerances of +/-1%. These lenses address various optical needs, from beam expansion and collimation to eliminating spherical aberration in complex optical systems.

Our germanium lenses also come with BBAR (broadband anti-reflection) coatings, which further enhance their performance, particularly in the desired wavelength range of 3-12 μm. These coatings maximize light transmission, reaching up to 95% in some cases.

Incorporating germanium transmits, which is a unique characteristic of this material, these lenses excel in mid-infrared light applications. The inclusion of AR coatings further boosts their transmission capabilities, allowing for superior image quality and clarity.

Among our offerings, plano-convex germanium lenses stand out for their utility in light collimation and focusing applications. These lenses find widespread use in diverse fields, including science, industry, and defense.

Our aspheric germanium lenses deserve special mention as they tackle the challenge of eliminating spherical aberration in optical systems, leading to simplified setups and even potential weight reduction in certain cases.

To ensure precision, our factory adheres to stringent standards for surface quality, achieving a 20-10 scratch dig rating, even after coating. This level of quality is suitable for most laser applications, guaranteeing reliable and high-performance germanium lenses for your needs.
