Wattsan UV TT

Wattsan markers use laser sources from Raycus, JPT and MAX Photonics — the leading Chinese manufacturers whose components are used in machines from TRUMPF, IPG and Coherent. The R series (standard fiber) delivers consistent power for deep engraving and annealing. The J MOPA series (JPT M7) adds pulse width control from 2 to 500 ns, enabling color marking on stainless steel, black marking on aluminum, and fine detail at very low power without burning.

All Wattsan markers use F-theta (flat-field) scan lenses that maintain constant focus across the entire working area — unlike standard lenses where corners defocus. The galvo-driven scanning mirrors move the beam at speeds up to 8000 mm/s, achieving marking cycle times measured in seconds. Standard field sizes: 100×100 mm, 150×150 mm, 200×200 mm, 300×300 mm — selected based on application requirements.

The UV series operates at 355 nm — a wavelength that most materials absorb regardless of color or surface finish. UV marking is a photochemical (cold) process with no heat-affected zone, making it the only viable choice for glass, transparent acrylic, ceramics, white plastics, medical packaging and sensitive electronics. It also marks all metals without the heat stress of fiber, making it the most universal wavelength in the Wattsan marker range.
