Beamera presents cost effective variable laser beam expander for medium power applications. It features three main advantages that help to stand out:
· Sturdy mechanical design
· Fine divergence adjustment
· Compact size
Variable expander features x1 to x3 range, that can be continuously zoomed along the range. Product is available for 1-st, 2-nd & 3-rd harmonics of both Neodymium and Ytterbium laser lines. Divergence adjustment solution is embedded in the system to allow for smooth and fine divergence adjustment compensation, which is crucial in laser machining process fine-tuning.
Expander is designed to comply strict stability, robustness and pricing requirements that are inflicted by industrial lasers applications, which makes it suitable for both – industrial and demanding scientific use.
Main applications for 1x-3x zoom beam expander are laser marking/engraving and laser microfabrication with moderate powers (e.g. surface structuring, 2 photon polymerization, cutting).
Estimated power levels that beam expander will work fine with:
-
1st harmonic ≤100W;
-
2nd harmonic ≤50W;
-
3rd harmonic ≤10W.
