Germanium also is opaque all over the complete obvious spectrum, which makes it ideal for programs where only IR transmission is wanted.
Our germanium lenses Possess a superior refractive index—the very best refractive index among readily available IR transmitters. What's more, it exhibits minimal chromatic aberration resulting from lower dispersion.
