When the beam interacts with the material s surface it alters the material s properties and appearance.
Laser marking meaning.
This concentrated beam targets only a specified area allowing the laser marking machine to create precise high quality high contrast marks that.
Maiman at hughes research laboratories based on theoretical work by charles hard townes and arthur.
Ppi and hz parameters.
This process is mostly used to create images on the material that may be seen at eye level.
To achieve a good result this should be the same or a multiple of the dpi selected in the print setting.
The first laser was built in 1960 by theodore h.
Laser engraving and laser marking is the practice of using lasers to engrave or mark an object.
Laser marking also known as laser engraving or laser etching is a marking method which utilizes laser light to mark materials using a fine spot diameter ranging from 0 002 to 0 01 the laser marks with short pulses 30 nanoseconds providing precise control and negligible heat input to the part.
Laser engraving is the practice of using lasers to engrave an object.
The ppi parameter pulses per inch determines how many laser pulses per inch are used for the engraving.
Laser marking works by using a focused beam of light to mark the surface of a material.
Laser marking on the other hand is a broader category of methods to leave marks on an object which also includes color change due to chemical molecular alteration charring foaming melting ablation and more the technique does not involve the use of inks nor does it involve tool bits which contact the engraving.
To do so the laser creates high heat that will vaporize the matter thus exposing cavities that will form the final image.
The mark settings object is used to change the laser settings within the marking sequence.
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation the term laser originated as an acronym for light amplification by stimulated emission of radiation.
Laser marking is what happens when the beam interacts with the surface of a material slightly altering its properties or appearance.
It is achieved by moving a low powered beam slowly across the material using a method called discoloration which creates high contrast marks without disrupting the material.
These properties distinguish laser engraving from alternative engraving or marking technologies where bit heads have to be replaced regularly or inks have to be used.
The technique does not involve the use of inks nor does it involve tool bits which contact the engraving surface and wear out.
Several mark setting objects may be used in a marking sequence especially if marking single line and true type fonts with shape or vector drawing objects in the same layout each type of marking object generally needs different laser settings to get the best performance.
A fast and clean technology laser marking is rapidly replacing older marking.
