Zoom Beam 1x – 3x Expander

Beamera presents a cost-effective variable laser beam expander for medium power applications. It features three main advantages that help it stand out from the competition:

• Sturdy mechanical design
• Fine divergence adjustment
• Compact size

The variable expander features a zoom range from x1 to x3 that can be continuously adjusted. The product is available for 1st, 2nd, and 3rd harmonics of both Neodymium and Ytterbium laser lines. A divergence adjustment solution is embedded in the system to allow for smooth and fine divergence adjustment compensation, which is crucial in the laser machining process fine-tuning.

The expander is designed to comply with strict stability, robustness, and pricing requirements imposed by industrial laser applications, making it suitable for both industrial and demanding scientific use.

Main applications for the 1x-3x zoom beam expander include laser marking/engraving and laser microfabrication with moderate powers (e.g., surface structuring, 2-photon polymerization, cutting).

Estimated power levels that the beam expander will work effectively with:

• 1st harmonic: ≤100W
• 2nd harmonic: ≤50W
• 3rd harmonic: ≤10W
