Our Portable lasers are the most powerful lasers we have and also the most powerful lasers in the industry. If other vendors said  their laser has a higher power with lower price, you must be careful. We guarantee that none are as stable.
Our Portable laser diode manufactured by OSRAM or NICHIA is encased in a sturdy aircraft grade aluminium shell that is hard anodized in black. In addition to its elegant and professional style, the outer case doubles as an effective heat-sink that helps dissipate heat buildup.
Portable laser lens is adjustable, by adjusting beam divergence, you will have full control of the laser’s spot size allowing the upmost convenience when tuning the laser for burning/heating, distance pointing, lighting, various experiments, and much more.
