摘要： A light source module (50) comprising a plurality of semiconductor emitters (110, 120, 130), each configured to emit a beam at a different peak emission wavelength. Each beam is divergent with a more divergent, fast axis and a less divergent, slow axis. First single-axis focusing elements (511, 521, 531) focus the beams from respective emitters in one of the fast and slow axis while the beams remain divergent in the other of the fast and slow axis. A beam combiner (240) based on dichroic mirrors (122, 132) is arranged to bring the beams from the individual first single-axis focusing elements into a common optical axis. A common second single-axis focusing element (750) is arranged to focus the combined beams output from the beam combiner in the other of the fast and slow axis which are then output from the light source module.

摘要： The present invention relates to a beam splitting device for a distal end section of an endoscope, wherein the beam splitting device comprises a first prism with a first entrance surface, a first internal incident surface and a first exit surface and a second prism with a second entrance surface and a second exit surface, and a dichroic beam splitting layer, wherein the first exit surface of the first prism and the second entrance surface of the second prism are adjacent, and the dichroic beam splitting layer is arranged between the adjacent surfaces so that incoming beams comprising first and second spectral regions are reflected by the first internal incident surface of the first prism, incident on the first exit surface of the first prism, and are split by the dichroic beam splitting layer into first beams of the first spectral region and second beams of the second spectral region for capturing separate images of the first spectral region by a first image sensor and of the second spectral region by a second image sensor in parallel. Furthermore, the invention concerns an objective system and an endoscope.

摘要： Provided is an invention related to laser beam shaping with the goal to achieve a controlled intensity profile, usually top-hat distribution, created by several laser beam sources with incident non-uniform beam intensity profile (incident gaussian laser beam/s or other higher order multi-transverse modes, in the visible, IR or UV spectrum).
The Laser beam homogenizer-expander uses a first beam shaper element to divide the incident beams into beamlets along the main optical axis, and a second beam shaper element i.e., 2nd light integrator which defines the top-hat intensity distribution output, thus providing a 2nd homogenization stage.
The invention also includes several light diffusers (F1, F2), mirrors, filters (D1, D2), and output lenses (L1, L2, L3), to achieve a good homogenization at the desired output angle which are described in detail in the following.
The invention is designed to fully integrate/blend one or several wavelength laser sources, like red, green, and blue as an example, but other wavelengths in the visible/non-visible spectrum can be integrated as well.
If multi-wavelengths are used as initial laser source (LS1), the light engine output provides a good homogenization and color blend, with almost no noticeable speckle, near top-hat intensity profile and no visible hot spots or interference patterns.
The invention is useful for many applications, like microscopy, material processing, fluorescence, lighting fixtures, holography, fiber coupling etc., where spectral properties of laser light is required (narrowband, monochromaticity) but a uniform distribution of the intensity is necessary at the same time.
