•Nd: YAG
•1064 nm
•40x40 mm to 100x100 mm marking area


Cheapest Nd: YAG laser marking system on the market today!


The RMI UM-1 Ultra-Compact Diode Pumped Nd:YAG laser marker is a very cost effective, turnkey, high performance system for marking and engraving applications. Ideal for small scale production environments.

Optional Class 1
Enclosure RMI’s Economy Laser Marking system delivers precision, non-impact marks on a variety of materials including metals and plastics. RMI’s laser marking systems offer a distinct advantage of a very short pulse width which minimizes the heat-affected zone (HAZ) while maximizing the contrast on the material being marked. With the ability to mark linear and elliptical text, barcodes, 2D Data Matrices, QR codes, serial numbers, logos, and photo-quality graphics, the Economy system has the versatility to meet almost any marking application.
