Why UV lasers can mark black on plastic
Dec 07 , 2023
Why UV lasers can mark black on plastic When a UV laser irradiates plastic, it causes its surface to turn black. The reason behind this phenomenon is that the laser emitted by the ultraviolet laser has high energy, which triggers a photochemical reaction when it hits the plastic surface. The energy of ultraviolet laser can break the chemical bonds in the plastic molecules, causing the...
