M-SHAPER

M-SHAPER PRODUCTS

HOLO/OR’s M-Shaper, is a diffractive optical elements (DOE) used to create a unique 2D M-shaped intensity profile, with sharp edges in a specific work plane.
The M-Shaper optical function is not possible by conventional reflective or refractive optical elements.
The typical application is to create a uniform exposure over scanned lines. That is, when scanning a line with a regular Gaussian or even Top-Hat spot the center gets over exposed (influencing the heat distribution during laser material processing).
The M-Shape is the mathematical shape that gives a uniform exposure over the line when scanned. This provides higher quality of the process & enables more flexibility in the system configuration.
For example, it allows optimization of the intensity profile, and image size, without changing the laser, fiber cable and/or scanning optical head.
The benefits of our optimized M-shaped intensity profile include:

• Uniform exposure over the scanned line
• “Cleaner” results with scanned lines in almost any process
• Enables very strong weld seams

The most M-Shape DOE’s listed below require a Single Mode (TEM00) input beam. However, some M-Shape DOE’s had been designed for Multimode lasers (with MM in remarks column). Please feel free to contact us on this or any other custom request you may have. 

FEATURES:

• Round M-Shape output profile (before integration)
• Uniform exposure over scanned lines
• Clearer defined edge
• High efficiency
• High power threshold
• Wavelengths from UV to IR
• Optional Ar/Ar coating

APPLICATIONS:

• Laser materials processing:
  • welding
  • cutting
  • scribing
• Strong weld seams (also in Plastics)
