InfraOptics supplies Zinc Selenide, Silicon, Germanium spherical lenses and aspherical lenses. We use laser based edging device to control MWIR and LWIR lenses’ decenter deviation, and test on reflective centering station to fulfill extreme precise tasks.
Germanium(Ge)
Germanium is the most common optical material, it can not only be used in long wave infrared but also medium wave infrared. Germanium should be careful treated in the process of light processing, coating and adjustment. Because the usage of germanium is wide, its problems can all be solved compared with its advantages.
Silicon(Si)
Silicon is a kind of crystal material similar to germanium. The refractive index of silicon is lower than germanium, it has enough advantage in controlling aberration. Besides, the dispersion of silicon is quite low. Silicon can be processed by diamond turning, but it is difficult and it is also harmful to turning tool. The common way to process is polishing.
Zinc selenide(ZnSe)
Zinc selenide also belong to infrared optical materials, zinc selenide is suitable for optical system that has less requirement for absorptivity.
Infrared lens are widely used in night vision goggles, imaging system and medical apparatus and instruments. InfraOptics is good at producing infrared lens of various materials, like germanium, silicon, zinc selenide.
