An optical observation instrument, in particular a spectacle, a reading aid or a telescope, comprises an optical element, in particular a spectacle lens, adapted to be controllably adjustable in its refractive power, a sensor, and a control unit for adjusting the refractive power as a function of signals from the sensor. The sensor is a brightness sensor. In a method of controllably adjusting a refractive power of an optical element in an optical observation instrument an optical parameter is captured by means of a sensor and the refractive power is adjusted as a function of a signal from the sensor. By means of the sensor the brightness of the light impinging on the optical instrument is captured.

A method for producing a shaped body () made of glass or glass ceramics comprises the steps of: (a) placing at least two glass blanks () side by side on a shaped surface () of a temperature-resistant sagging mold (); (b) sagging the glass blanks () onto the shaped surface () by heating the sagging mold () and the glass blanks (); (c) attaching the sagged glass blanks () to each other in order to form the shaped body (); and (d) lifting the shaped body () from the sagging mold (). A shaped body () comprises at least two glass blanks () attached side by side and formed by sagging.

An apparatus for polishing an optical surface, in particular an optical surface of a spectacle lens, is disclosed. The apparatus comprises a polishing head having a polishing tool, the polishing tool being provided along a common axis, one behind another, with a first preferably rigid member, a second elastic member, and a polishing lining, each extending essentially radially relative to the axis. The second elastic member is configured to be increasingly soft in a radial outward direction. Moreover, a method of polishing an optical surface, in particular a surface of a spectacle lens, an optical component manufactured according to that method, in particular a spectacle lens, as well as a method of manufacturing a polishing tool are disclosed.

A method of making a fracture-resistant large-size calcium fluoride single crystal is described, which is suitable for an optical component for radiation in the far UV range. The calcium fluoride raw material for the single crystal is first melted and subsequently solidified by cooling the melt to form a single crystal. However the calcium fluoride raw material is doped with from 1 to 250, preferably 1 to 100, ppm of strontium, preferably added as strontium fluoride, and contains from 1 to 10 ppm of sodium as well as up to 100 ppm of other impurities.

A method and a device for determining the resistance of an optical material to radiation damage, wherein several sample volumes ( ) within the optical material are simultaneously irradiated with test radiation having differing, measured or preset radiant-energy densities. The radiation employed for all sample volumes comes from a common radiation source ( ) and at least one parameter indicative of the resistances to radiation damage of the irradiated sample volumes is measured using measuring radiation. The measuring radiation also comes from the same radiation source that supplies the test radiation and the material's resistance to radiation damage is determined based on a functional relation between its radiation-damage-resistance parameter and the radiant-energy densities, wherein that functional relation is determined using the values of the radiation-damage-resistance parameters measured for the various sample volumes for the various radiant-energy densities employed. Such a method and device have application, e.g., in determining the resistances of CaF and other optical materials to damage by ultraviolet laser radiation.
