Germanium Plano-Convex Lens

Current model: SSK-PCX-Lenses-Ge

Germanium is a commonly used optical glass material in the infrared spectral range, with a transmission window of 2.0–16 μm. It features a high refractive index and exceptional Vickers hardness. Germanium exhibits chemical inertness toward air, water, acids, and alkalis, making it well suited for thermal imaging and infrared imaging in harsh environments. It can serve as a substrate for various optical components, such as lenses and windows. A plano-convex lens focuses light to a single point; it has a positive focal length, with one surface flat and the other convex. It is often employed for collimation and focusing of monochromatic light sources. When in use, the convex side should face the incoming light. When combined with other lenses, germanium plano-convex lenses can be utilized for beam shaping, beam collimation, beam expansion, beam reduction, and a variety of other applications.

Germanium Plano-Convex Lens

Germanium Plano-Convex (PCX) Lenses are plano-convex lenses with a germanium substrate.
Germanium is a commonly used optical glass material in the infrared spectral range, with a transmission window of 2.0–16 μm. It features a high refractive index and exceptional Vickers hardness. Germanium exhibits chemical inertness toward air, water, acids, and bases, making it well suited for thermal imaging and infrared imaging in harsh environments. It can serve as a substrate for various optical components, such as lenses and windows. A plano-convex lens focuses light to a single point; it has a positive focal length, with one surface flat and the other convex. It is often employed for collimation and focusing of monochromatic light sources. When in use, orient the convex side toward the incident light. When combined with other lenses, germanium plano-convex lenses can be utilized for beam shaping, beam collimation, beam expansion, beam reduction, and a variety of other applications.
United Optics’ germanium plano-convex lenses are available in a wide range of sizes and focal lengths, with both coated and uncoated options. Our broadband anti-reflection coatings are optimized for the IR2 (infrared 8–12 μm) spectral band, meeting the diverse application requirements across various wavelength ranges and scenarios. United Optics can also customize lenses to other specifications tailored to your specific needs.
