Publication number: 20170219811Abstract: The invention relates to a method for illuminating an object in a digital light microscope, to a digital light microscope, and to a bright field reflected-light illumination device for a digital light microscope. According to the invention, the bright field reflected-light illumination and the dark field reflected-light illumination are configured with light-emitting diodes as light sources and are individually or jointly drivable via a control unit. Both the bright field reflected-light illumination and the dark field reflected-light illumination are configured as “critical” illumination, in which the light source is imaged into the object plane.Type: ApplicationFiled: April 12, 2017Publication date: August 3, 2017Inventors: Hans TANDLER, Johannes KNOBLICH, Dominik STEHR, Alexander GAIDUK, Enrico GEIßLER, Jan BUCHHEISTER, Max FUNCK

Publication number: 20170206822Abstract: Each modulator of an image projector includes multiple pixels arranged in rows and columns, switchable independently of each other into a first state, in which light incident on them is used to generate an image, and into a second state, in which light incident on them is not used to generate an image. At least one first pixel is assigned to each second pixel such that the imaging optical system a) strikes the second pixel with light from the respective assigned first pixel when the assigned first pixel is switched into the first state, in order to illuminate the second pixel actively, and b) does not strike the second pixel it with light from the respective assigned first pixel when the assigned first pixel is switched into the second state, in order not to illuminate the second pixel actively. A control unit that controls the modulators is also disclosed.Type: ApplicationFiled: January 13, 2017Publication date: July 20, 2017Inventors: Bryce Anton MOFFAT, Christoph NIETEN, Enrico GEIßLER, Alexander GRATZKE, Axel KRAUSE
