  • Patent number: 11892614
    Abstract: Light source device comprising a light source and an optical component, wherein the optical component comprises a receiving section for receiving light from the light source and an emitting section for emitting light, wherein the light source is a non-coherent light source and is adapted to emit light from a two-dimensional region and wherein the optical component is adapted to guide the light from the receiving section to the emitting section such that the light can be emitted in a one dimensional pattern at the emitting section.
    Type: Grant

  • Patent number: 9581798
    Abstract: Light sheet microscope for recording 3D images of a specimen, comprising a light sheet generator, an objective lens, an image detector and a wavefront encoder element or system positioned between the objective lens and the image detector for extending the depth of field of the objective lens. By doing so, the restriction on the distance between the collecting objective and the light sheet is relaxed, allowing the use of a light sheet scanning unit. The resulting light sheet microscope allows for a robust, aberration insensitive, fast 3D imaging without the need to move or perturb the specimen.

  • Patent number: 9454060
    Abstract: A mode locked semiconductor disk laser with an output beam having an ultra-short pulse length which provides the incident beam to a non linear microscope. The wavelength of the beam is at or near the action cross section maximum absorption wavelength for creating two photon excited fluorescence of a fluorescent biological marker in a sample. Semiconductor disk lasers combine excellent beam quality and output power, stability while maintaining simplicity and easiness of operation. In addition, these types of lasers are ideally suited for mass production as they are built in wafer-scale technology enabling a high level of integration. Importantly this non expensive, turn-key, compact laser system could be used as a platform to develop portable non-linear bio-imaging devices for clinical studies, facilitating its wide-spread adoption in “real-life” applications.

  • Patent number: 9304310
    Abstract: A STED microscope for producing a 3D image. The microscope has an excitation laser source for providing an excitation laser beam and a depletion laser source for providing stimulated emission depletion laser beam. The excitation beam is capable of exciting fluorescent markers in a sample placed in the sample region and the depletion beam is capable of inducing stimulated emission in the fluorescent marker in the sample in a region around the excitation beam to restrict the size of the region within which the fluorescent markers are excited and wherein the depletion laser source goes through an optical element which creates a cone refractive pattern which induces stimulated emission in the fluorescent marker in the sample. The shape of the light hollow of the cone refractive pattern varies at different distances from the source. This depth profile can be used to distinguish between positions at varying depths within a sample to create a 3D image.
