Germanium Lenses

Quantity : 10 pcs-500   Price : $40-$200

Ge Lenses

In the range of 2-12 μm, germanium is the most commonly used material for the production of spherical lenses and germanium ir windows for high efficiency infrared in the imaging system. Germanium has a high refractive index (about 4.0 through 2-14μm band), usually do not need to be modified due to its low chromatic aberration in low power imaging systems.

Germanium optical performance is severely affected by temperature; the transmission rate decreases with the increase of temperature, most applications with Germanium elements involved can only be applied below 100 degrees Celsius. Designers also need to pay attention for certain weight constraints in system design 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 promising finish and good transmittance. Hyperion Optics provides 40-20 surface quality Ge lenses as factory standard products, with up to 1/4 lambda in surface accuracy. Our outstanding CNC lathe capability has leveraged our machining efficiency to meet rapid delivery. Ge aspheric infrared 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 Ge aspheric zoom lens for more information.
