The combination of high-tech laser marking head and portable construction make VML-10FHS an outstanding hand-held engraving/marking machine. The design involves modules with a portable laser head that works great with bulk materials. The high-quality laser head provided offers highly stable high-frequency pulse beams that provide high accuracy at faster speeds needed for exquisite markings. Further, the advanced protective covering provides fine focal length adjustment, with apertures reaching close to the diffraction limit. The specifications of the laser beam include a spot diameter less than 20µm, M square close to 1, divergence angle less than a quarter of that of diode lasers, power surge per pulse below 1%, and operation in fundamental transverse to TEM00 mode.
