Description

Positioning laser kit 25 mW GREEN "cross hair"

25 mW Green "Cross Hair" Positioning Laser Kit – PLM-SET-25-520-CH: A ready-to-use kit that projects a green cross hair (520 nm) onto the work surface. The cross hair marks an exact target point with a center and axes—for example, for positioning workpieces on machines. The 25-mW output stage provides maximum green visibility even in bright environments.

  • "Cross hair" projection pattern via DOE digital optics
  • Projection pattern in green (520 nm) with 25 mW
  • Calibrated and ready for use; focus and line position adjustable
  • Connection options ranging from 12–25 VDC to 230 V with plug-in power supply

The kit is based on the MediaLas modular system in a compact 12-mm module format: The focus (line width at the point of impact) is adjusted directly on the module via the front ring, and the precision optics can be replaced at any time—even when installed. Various mounts are available for installation, ranging from a mounting block to a vibration-resistant 3D ball-head mount; the module is simply clamped into place and can be adjusted in all directions.

Set consists of

  • 12 × 42 mm positioning laser module with DOE “cross hair” optics (520 nm, 25 mW), pre-calibrated and ready for use
  • Power cable in the selected connection variant (230 V version includes a matching plug-in power supply)

Electrical connection

230 V version: Power cable with a hollow connector and a matching plug-in power supply included in the set. 12–25-V version: Flexible connection cable with open ends and wire end ferrules for direct connection to a power supply or busbar; for the 24-V version, a small adapter is heat-shrunk onto the cable. Reverse polarity protection is integrated.

Pick-by-light is an optical guidance system used in logistics and assembly: a laser shows the worker the next position to pick or the location of the next work step. Instead of reading lists or checking screens, the worker simply follows the laser. Benefits: fewer pick errors, faster cycle times, shorter training, low noise. Used in: order-picking warehouses (picking from shelf compartments), manual assembly (which screw next), placement (which position on the workpiece), packing (which box gets the item). Our DOE positioning lasers are well suited because they project clearly visible, defined patterns.
The image size scales linearly with distance. With a PLM module at approx. 30° opening angle, 1 m distance gives an image of around 30 cm diagonal. At 2 m this doubles to 60 cm; at 0.5 m it halves to 15 cm. Recommended operating distance: 5 cm to approx. 100 cm. Beyond 100 cm the line sharpness drops noticeably, because DOE optics widen the line proportionally with distance. For very large distances we recommend the FloorPoint (100 mW at 532 nm) or an ILP laser projector.
We offer five standard patterns: Laser crosshair „CH“ – classic +-cross for centring. Circle „Circle“ – marking circular areas (e.g. drill positions). Search field „SF“ – a larger highlighted area for visual orientation. Square „SQ“ – rectangular marking for pallet positions or boxes. Dot grid – on request for special patterns such as pick grids. The standard patterns are encoded in the product codes (e.g. PLM-30-650-CH = crosshair, PLM-10-650-SQ = square). Custom DOEs with company-specific logos or special alignment marks are available on request.
Classes 1M and 2M according to EN 60825-1 stand for „Magnifying Optics“ – lasers that are safe under normal conditions but whose radiation can become hazardous when viewed through optical aids such as magnifiers, binoculars or microscopes. With DOE positioning lasers the optical power is spread across the pattern – but if a lens were to refocus the radiation, the power density could reach hazardous levels. Practical consequence: safe for normal industrial use without safety goggles. Prohibited: viewing the beam through magnifiers, binoculars or microscopes.
Classic lens optics (cross-line laser): very sharp, narrow lines; brightest at the centre, fading towards the line ends (Gaussian profile). Ideal for precise centring where line sharpness is critical. DOE optics (positioning laser): even brightness across the entire pattern, defined outer boundary, arbitrary patterns possible. Lines are inherently a little wider and less sharp than with lens optics. When to choose which? Classic optics for micrometre-level centring and microscope work. DOE optics for operator guidance, pick-by-light and anywhere the whole pattern must be evenly visible.
A DOE – diffractive optical element – is a special optic that generates a pattern through diffraction rather than through classic refraction at lenses. Instead of just a single line or dot, arbitrary patterns are formed: crosshairs, circles, squares, search fields, dot grids or marking symbols. The advantage over classic lens optics: constant brightness across the entire pattern area – even the outer edges of a crosshair are as bright as the centre. The trade-off: lines are inherently a little wider than with classic lens optics. DOE modules are ideal for operator guidance, pick-by-light and position indication.
