SED-420JDM-G is an air-cooled fiber laser marking machine using a highly integrated pulsed fiber laser source. Excellent TEM00 beam quality (small divergence angle) makes it ideal for precision and fine marking. 1064 nm
مبدأ العمل
A laser-diode-pumped fiber laser source generates a 1064 nm pulsed beam(30 W average, 30–60 kHz modulation, TEM00 mode). The beam passes through an isolator and beam expander into a high-speed digital galvanometer pair(X/Y mirrors) that steers it through a Wuhan-made F-theta field lens, focusing the spot anywhere within the selectable marking field(70×70 to 300×300 mm). A red diode pilot beam coaxial with the IR laser provides visible alignment indication. The LEADJET PC/touchscreen control system sends vector instructions for text, graphics, logos, 1D/2D codes; the galvos paint the pattern at up to 7000 mm/s with 0.003 mm repeat accuracy. Laser ablates/oxidizes or annealing-darkens the surface — producing permanent, high-contrast marks with no consumables and no contact. Forced air(fan) cooling keeps the fiber source within spec at 0–35 °C ambient.
