  • Patent number: 11612468
    Abstract: The invention relates to a polymerization and post-tempering device (10) for tempering, in particular post-tempering, dental restoration parts (54) made of polymerizable plastics. At least one light source (38) which emits light in the visible and/or ultraviolet wavelength range and a light chamber with a door (14) to the light chamber are provided. The door (14) comprises a window (20) with a window pane (22) which consists of at least two layers (56, 58) whose layer facing the light chamber reflects at least 90%, in particular approximately 95%, of light, and whose layer facing away from the light chamber filters out UV light and/or blue light.

  • Patent number: 11351722
    Abstract: The present invention relates to a stereolithography device (100) comprising a light source (101) for emitting light to cure a light-curing material (121); a sensor (103) for determining an actual value of the light intensity of the emitted light; and a control unit (105) for adapting the electric current through the light source (101) until the actual value of the light intensity reaches a specified desired value.

  • Patent number: 9658442
    Abstract: The invention describes a method and a microscopy system for imaging and analyzing stochastically and independently blinking point-like emitters. A multiple-order cumulants analysis in conjunction with an established blinking model enables the extraction of super-resolved environment-related parameter maps, such as molecular state lifetimes, concentration and brightness distributions of the emitter. In addition, such parameter maps can be used to compensate for the non-linear brightness and blinking response of higher-order cumulant images—used for example in Super-resolution Optical Fluctuation Imaging (SOFI)—to generate a balanced image contrast. Structures that otherwise would be masked by brighter regions in the conventional cumulant image become samples using spectral cross-cumulants.
