Presentation of the equipment's characteristics

The Greenstone-Tech GST-Series Cultural Relics Laser Cleaner is a pulsed solid-state laser cleaning system designed for heritage conservation and metal artifact restoration. Using a high single-pulse energy up to 1 J (1000 mJ) and an intelligent control system, it removes surface contaminants such as oil stains and rust from cultural relic metal surfaces with minimal thermal impact and non-contact precision.

With a beam homogenization design, the system delivers a more uniform spot for consistent cleaning results and stable long-duration operation. It also supports dual wavelengths (532 nm & 1064 nm) and can be configured with an optional frequency-conversion module to match different restoration needs.

processed samples

  • Designed for heritage conservation: Suitable for removing oil, oxidation, and rust on metal cultural relic surfaces while helping reduce the risk of substrate damage.

  • High single-pulse energy (up to 1 J): Strong cleaning capability for stubborn contamination layers.

  • Dual-wavelength flexibility (532 nm & 1064 nm): Broader adaptability across different contaminants and surface conditions; frequency conversion module optional.

  • Uniform beam output: Built-in beam homogenization helps improve spot consistency and cleaning uniformity.

  • Stable long-term operation: Power instability < 2%, supporting consistent results over time.

  • Wide process control: Energy adjustable from 10% to 100%, enabling fine control for delicate restoration tasks.

  • Articulated light-guide arm output: Uses a light-guide arm for controlled delivery during cleaning operations.

  • Water-cooled design: Supports stable performance during extended duty cycles.
