Abstract: The invention relates to a measuring probe for scanning light beams (10) or laser beams. The measuring probe is suitable for scanning laser beams with very high power and for determining geometric parameters of a light beam (10) with high spatial resolution. For this purpose, a device is proposed which comprises a body (20), a probe area (30) and a detector (40). The body (20) is made of an optically transparent material and has a light beam entry surface (22), a light beam exit surface (23) and a detection light exit surface (25). The light beam entry surface (22) and the light beam exit surface (23) are for the most part smooth and polished. The body (20) includes the probe area (30) having light-deflecting structuring. The detector (40) is designed to detect at least part of the beam portion (15) deflected from the light beam (10) by the probe area (30). The body (20) and the light beam (10) are movable in two different directions of movement (51, 52) perpendicular to the direction of the axis (11) of the light beam (10) relative to each other. The probe area (30) has a shape whose two-dimensional projection on a surface perpendicular to the axis (11) of the light beam (10) approximately the same dimensions in the two different directions of movement (51, 52) perpendicular to the axis (11) of the light beam (10).

Abstract: An apparatus for the determination of geometric parameters of a laser beam, such as, for example, the beam diameter or the focus diameter. The apparatus includes a device for the emission of a laser beam into an active region, a detector arrangement, which can be positioned in the active region, a device for the provision of a relative movement between the laser beam and the detector arrangement, and a device for the registration and evaluation of a temporally varying signal of the detector arrangement. The detector arrangement includes at least one light guide, at least two flight-diffusing structures, and at least one light-sensitive sensor. The light guide has a light-emitting surface and a light-conducting region, with an elongated shape. The at least two light-diffusing structures are essentially extended along two different directions.

Abstract: An M2 value beam profiling apparatus and method is described. The M2 value beam profiler comprises an optical axis defined by a focussing lens assembly and a detector, wherein the focussing lens acts to create an artificial waist within an optical field propagating along the optical axis. The beam profiler also comprises a multiple blade assembly having a first set of blades located at an artificial waist position and a second set of blades longitudinally separated along the optical axis from the artificial waist position. The multiple blade assembly therefore provides a means for selectively passing the blades through the location of the optical axis. Employing these measured widths allows for the M2 value of the optical field to be determined.

Abstract: A method and a gonioradiometer for the direction-dependent measurement of at least one photometric or radiometric characteristic of an optical radiation source. The emission direction of the photometric or radiometric characteristic is described using a system of planes (A, B, C), the planes of which intersect at an intersection line which passes through the radiation centroid of the radiation source, and using an emission angle (α, β, γ) which specifies the emission direction (α, β, γ) within a considered plane. A sensor or the radiation source is fastened to a multi-axis articulated robot. The robot is configured to only swivel about precisely one of its axes during a measuring process, in which measurement values relating to different emission angles (α, β, γ) within a considered plane of the system of planes (A, B, C) or to different planes at a considered emission angle (α, β, γ) are detected.
