Custom Dual-Wavelength Non-Ablative Laser Cleaning Machine (Cultural Heritage & Precision Cleaning)
Presentation of the equipment's characteristics
The Greenstone GST-DW Series Dual-Wavelength Non-Ablative Laser Cleaning Machine is a precision laser cleaning solution engineered for cultural heritage conservation and high-value surface restoration. By combining dual wavelengths (532 nm & 1064 nm) with a beam-homogenized output and intelligent energy control, it removes contaminants while helping minimize substrate impact—ideal for cleaning rust, soot, oxides, stains, grime, graffiti residues, and surface pollutants on sensitive objects. Designed for professional restoration workflows, the system supports stable long-term operation and consistent cleaning quality for museums, laboratories, and industrial precision applications.
Dual-Wavelength Selectivity (532/1064 nm): Switch wavelengths to better match different materials and contamination layers for more controllable, safer cleaning.
Non-Contact, Low-Damage Cleaning: No mechanical abrasion and no chemical solvents—reduces risk of secondary contamination and helps protect fragile surfaces.
Beam Homogenization for Uniform Results: Optimized optical design delivers a more even spot profile, improving consistency and reducing local overheating.
Precision Control for Conservation Work: Energy adjustable (10–100%), spot size adjustable (1–10 mm), and low repetition rate (1–10 Hz) support careful, step-by-step cleaning.
Guided-Arm Output for Complex Areas: Light-guide arm output is suitable for detailed work on shaped parts, recesses, and hard-to-reach surfaces.
Stable, Reliable Performance: Designed for professional environments with solid structural design and stable output control for repeatable cleaning quality.
