Dear friend,
Nice day!
I'm Ellen from LASERWAVE, I would like to show you LASERWAVE'Supgraded 520nm green laser.
Compared with DPSS 532nm, 520nm will be the trend in near future. 520nm is more stable, its linear analog is better and its lifetime is longer . The beam and divergence of upgraded 520nm had won a very good reputation among customers. Here attach pictures for your reference. Would you plan to have one for testing? If so, pls contact with me at email: Salesteam2@laser-wave.com/marketing@laser-wave.com Or leave your eamil address or skype, I will reply you soonest.
Best regards!
Ellen
