  • Optical arrangement with an f-theta lens
    Patent number: 12601894
    Abstract: An optical arrangement for a laser beam includes an f-theta lens. The f-theta lens is disposed in a divergent beam path of the optical arrangement in order to focus the laser beam into a focus plane. The focus plane is located at a distance from a focal plane of the f-theta lens.
    Type: Grant

  • Laser line illumination
    Patent number: 11759886
    Abstract: A laser system is configured for providing a laser line in a working plane for line illumination of an object. The laser line extends in a first direction over a significant length and in a second direction over a small extent. The laser system comprises a laser source for providing a laser beam as basis for an elongated input laser beam propagating along a propagation direction, and a homogenization and focussing unit for homogenizing the elongated laser beam to form the laser line. The laser system is in particular suitable for providing a laser line that can be stitched to another laser line of a respective further laser system.

  • Laser line illumination
    Patent number: 11407062
    Abstract: A laser system is configured for providing a laser line (L) in a working plane (WP) for line illumination of an object. The laser line (L) extends in a first direction (x) over a significant length and in a second direction (y) over a small extent. The laser system includes a laser source for providing a laser beam as basis for an elongated input laser beam propagating along a propagation direction (z), and a homogenization and focusing unit for homogenizing the elongated laser beam to form the laser line (L). The laser system is, for example, suitable for providing a laser line (L) that can be stitched to another laser line (L?) of another laser system.
