Germanium Lenses
In the range of 2-12 μm, germanium is the most commonly used material for the production of sphericallensesand windows forhigh efficiency infrared in the imaging system. Germanium has a high refractive index (about 4.0through 2-14μm band), usually do not need to be modified due to its low chromatic aberration in low power imaging systems.
Germaniumoptical performanceis severely affected by temperature; the transmission rate decreases with the increase of temperature, most applications with Germanium elements involved can only be applied below100 degrees Celsius. Designers also need to pay attention for certain weight constraints in systemdesign with a density of germanium (5.33 g/cm3). Germanium is mainly used in the thermal imaging system and infrared (FLIR) field.
It is critical that the surface of the material has a promisingfinish and good transmittance. Hyperion Optics provides 40-20 surface quality Ge lenses as factory standard products, with up to 1/4 lambda in surfaceaccuracy. Our outstanding CNC lathe capability has leveraged our machining efficiency to meet rapid delivery. Ge aspheric lenses stand up well to harsh environments and we offer the most popular sizes with Anti-Reflection Coatings. are also available for your application;please refer us Aspheric Lensesfor more information.
