Germanium Plano-Convex Lenses feature precision diamond turned surfaces, making the Germanium Lens ideal for a variety of infrared applications, including thermal imaging, infrared spectroscopy, and remote sensing.
The transmittance range of optical germanium material is 2-14um, and its refractive index is as high as 4. Germanium lens and germanium window are widely used in thermal imaging system. Germanium Aspheric Lens are available upon request.
GE material feature high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended on these germanium lens and Ge windows for sufficient transmission in the region of interest.
Other Infrared Optics Lens such as Zinc Sulfide Lens, Zns Spherical Lens, Calcium Fluoride Lens, Silicon Lens are available upon request.
