UV Laser Marker Introduction

UV laser marking machines are the current players that have made a permanent place for themselves in the world of today. The marks on medicine packaging and on the tablets themselves are made by a laser. Furthermore, the complex safety features on ID and credit cards are made by laser and eyeglasses have almost invisible marks made by the same technology. The lasers in use for these applications are ultraviolet (UV) lasers that generate light with wavelengths in the range of 150 to 400 nm

But what is a UV laser and how is it in use for marking? We will discuss this and much more below. Our discourse will range from the technologies at play to its uses in the marking world and a few key UV lasers marking machine manufacturers gripping the industry today.

The World of UV Lasers

Laser technology has been in use for marking materials for quite some time and one can say the market is mature to an extent. This assessment is based upon the fact that many versatile solutions are available to cater to industrial needs.

For instance, handheld laser markers are available for marking extremely heavy or large objects. Similarly, solutions that can integrate with a conveyor setup exist to facilitate production lines. Within the laser segment exist several technologies and are in use according to the benefits they offer. These benefits can range from the type of materials they can mark to the precision and sensitivity they offer. UV lasers are a sub-category of this domain.

The wavelength of UV laser light is around one-third (355 nm) of that of standard wavelength lasers (1064 nm). Moreover, the name “UV laser marker” comes from its wavelength being in the ultraviolet portion of the light spectrum.

A: Ultraviolet range 

B: Visible range 

C: Infrared range

UV Laser in the Industry 

The design of a UV laser allows it to be a practical solution for marking plastics and glass. Moreover, the UV laser machine can engrave a vast number of materials, from metals to paper. Following is a basic list of mater
