High-Precision Chromatic Laser Processing Equipment for Gradient Rainbow Effects
Colorful laser processing equipment is an advanced precision machining technology based on laser microstructuring or interference effects. By utilizing high-energy pulsed lasers to create nano-scale microstructures or selective oxide layers on material surfaces, it achieves dynamic color changes, gradient rainbow effects, or metallic luster through light interference, diffraction, or reflection. Its core advantages include non-contact processing, micron-level precision, and eco-friendliness, making it widely applicable in consumer electronics, automotive interiors, luxury packaging, and jewelry design.
Chromatic Laser Processing Equipment Working Principles
1. Laser Microstructuring:
- Cold Processing (UV Laser): High-energy pulses create micron-scale pits or stripes on surfaces, altering reflectivity to produce interference effects (e.g., RuiFengHeng D9-355 etching semi-transparent oxide layers on plastics).
- Thermal Processing (IR/Fiber Laser): Selective melting/vaporization generates periodic microstructures (e.g., IPG YLPP creating nano-gratings on metals for diffraction-based color shifts).
2. Color Generation Mechanisms:
- Thin-Film Interference: Oxide films on stainless steel create rainbow hues via wavelength-specific light interference (e.g., Baiyi Laser’s MOPA technology).
- Diffraction/Scattering: Nanostructures from ultrafast lasers scatter light directionally, producing angle-dependent colors (e.g., holographic textures on jewelry).
