What Is UV Laser Marking? (Technical Guide for Precision and Micro Marking)
UV laser marking is an advanced laser technology that operates with high precision and low heat impact thanks to its short wavelength. UV laser systems with a wavelength of 355 nm are especially used for micro marking applications on plastics, glass, and sensitive electronic components. Also called “cold marking,” this method prevents deformation by applying minimal thermal impact to the material surface. This guide explains in detail the working principle, advantages, and application areas of UV laser marking technology.
