UV Marking & Coding
A 355 nm pulsed ultraviolet source marks through a cold, low-heat process instead of burning the surface, so glass, LCD panels, silicon wafers, sapphire and heat-sensitive plastics take a fine, clean mark. Supplied as a flying coder, a desktop cabinet or a cordless handheld unit.
Range
Formats & Power Options
Three formats share the same 355 nm pulsed UV source. Choose by how the part reaches the beam.
Flying UV coder · 3–10 W
In-line coding onto a moving conveyor, reaching 200 m/min on single-line 2 mm characters. A JPT pulsed UV source in a 660 × 510 × 1460 mm cabinet, about 89 kg including the chiller. Air-cooled or with an external industrial water chiller, depending on the configuration.
Desktop UV marker · 3–20 W
A floor-standing cabinet at 800 × 660 × 1425 mm and about 100 kg, configured with a DXT, Maiman or JPT pulsed UV source, a dual red-light metal galvanometer, an industrial PC and a display. This format carries the widest power range and the finest line width.
Handheld UV marker · 3–5 W
A cordless unit on a 24 V lithium battery for 2–3 hours of use, built around a CRS pulsed UV source. The head weighs 8 kg and the complete machine 11.85 kg, with a 100 × 100 mm field and red-light preview focusing.
Why UV
Built for Heat-Sensitive Materials
At 355 nm the pulse acts on the surface with very little heat transfer into the part, so the mark forms with almost no heat-affected zone — usable on glass, silicon, sapphire, thin ceramics and polymer films that a longer wavelength would scorch or crack.
Glass, LCD panels, silicon wafers, IC dies, sapphire, polymer films and heat-sensitive plastics take a fine mark without burning or deforming.
The pulsed UV source is rated at roughly 20,000 working hours, with output power stability held within 3%.
The flying format keeps up with a running conveyor on single-line 2 mm characters, for cable, pipe, film and bottle-cap coding.
The handheld format runs off a 24 V lithium battery, with an 8 kg head for parts that cannot be brought to a bench.
What It Is
What Is a UV Laser Marking Machine?
A UV laser marking machine takes a 1064 nm fiber or solid-state beam and converts it to 355 nm in the third harmonic, then steers that short-wavelength pulse across the part with a galvanometer scanner. Because the shorter wavelength is absorbed in a very thin surface layer, the mark is produced with minimal heat spreading into the material, which is what makes it usable on glass, wafers and thin plastic film. The same source is supplied in three formats — a flying coder over a conveyor, a desktop cabinet for batch work, and a cordless handheld unit.

Field size, marking depth and achievable contrast depend on the material and on marking time. Machines are configured per application — send a sample specification and we will confirm the working figures.
Applications
Applications & Use Cases
UV marking is chosen where the material will not tolerate heat, or where the code has to stay legible at a size the eye can barely resolve — packaging, cable, glass and electronics.
Comparison
Comparison & Selection Guide
Two questions decide the wavelength, and one more decides the format: what is the material, how fine is the mark, and does the part move.
Power sets throughput and mark contrast rather than the range of materials the machine will mark. If you are unsure, send a sample part and a target cycle time.
