  • Holding device for an optical element made of a crystalline material
    Patent number: 6667839
    Abstract: A device is used to hold an optical element, in particular one made of a crystalline material, in particular of CaF2, while the optical element is being coated, in particular by the vapor-deposition of at least one functional layer in a vacuum coating plant. The latter has a device for mounting the optical element, it being possible for the optical element to be heated in the vacuum coating plant via suitable radiation, in particular infrared radiation. An intermediate element which has a lower thermal absorption than the device for mounting the optical element is arranged between the device for mounting the optical element and the optical element.
