Germanium Rods, Germanium Rod Lenses

    Creator Optics offers a variety of custom infrared germanium rods and rod lenses. These rods are of the following types: all-surface-ground germanium rods, all-surface-polished germanium rods, cylindrical-surface-polished germanium rods and two-end-surface polished germanium rods.

    All-surface-ground germanium rod has good grinding surfaces. In addition to the two end surfaces, the cylindrical surface, chamferface also has a good grinding. It has precise dimensions and geometry.
    All-surface-polished germanium rod has deep polished surfaces. Optical polishing of two end surfaces, cylindrical surfaces and even chamfers. The diameter tolerance can be controlled at +/-0.01mm, the surface quality of polished surfaces can be up to 40/20.
    Cylindrical-surface-polished and two-end-surface polished germanium rods are similar to all-surface-polished germanium rod. All of these polished germanium rods can be used as infrared rod lenses.
