Product Lineup
MD-X laser markers are versatile, general-purpose systems for marking and processing a wide range of materials. These powerful hybrid marking systems boast an internal vision system, full-field autofocus and marking analytics tools.
MD-U UV laser markers are designed for high-contrast, damage-free marking applications. UV lasers excel at marking plastics, glass, and other heat-sensitive materials. The MD-U's marking head contains an embedded multi-function camera that can autofocus to a part, check-marking quality, and read 2D codes.
MD-F fiber laser markers are high-powered machines designed for deep engraving and high-speed processing. 3-Axis scanning and on-the-fly focal adjustments give the MD-F series a leg-up over conventional laser engravers.
ML-Z CO2 laser markers are incredibly versatile. They can mark opaque objects like paper, wood, rubber, ceramics, and transparent objects like glass. CO2 lasers are also used for gate cutting, drilling, and decapsulation.
MD-T green laser markers use an integrated telecentric lens to keep the laser beam perpendicular across the entire marking surface. This ensures micron-level marking and processing throughout the target area.
Simply put, laser markers use high-energy light to mark the surface of a part. Laser markers vary by the wavelength of light, and different wavelengths are optimized for marking and processing different materials.
The majority of industrial laser markers are YVO4 lasers, fiber lasers, UV lasers, and CO2 lasers.
Laser markers are used to permanently mark text, logos, barcodes, or 2D codes on parts in all industries. Common marking types include oxidizing, annealing, engraving, etching, discoloration, and processing.
Benefits of Laser Markers
Inkjet and pad-printing systems leave impermanent marks that can be rubbed off or fade away. Laser marking does not wear off or contaminate the product being marked.
Because laser markers use light to directly mark products, there is no need to purchase consumables, clean print heads, or perform other routine maintenance tasks that are necessary with conventional ink and label marking methods. This also helps reduce associated maintenance costs.
Typical systems can only mark in 2 dimensions (X and Y). KEYENCE laser markers have 3-axis beam control, allowing them to mark across a larger area, compensate for part variation, and correct for mounting restrictions with zero physical equipment adjustments.
For industries that use shot blasting for strengthening parts, laser markers can be a solution for ensuring shot blast-resistant marks. Laser markers use engraving to create 2D codes that do not get fully tarnished with shot blasting.

Frequently Asked Questions About Laser Marking Systems / Laser Markers
Laser markers work by scanning a focused beam of high-energy light across the surface of a part in the desired pattern. Different contrast, depths, and surface finishes can be achieved depending on the laser wavelength and part material.
Laser marking causes discoloration on the surface of a part, whereas laser engraving actually removes material and "digs in" to a part.
Practically speaking: no. Laser etchers interact directly with the surface of a part, so the only real way to remove a laser mark is to remove the material it's on.
With a variety of different models and wavelengths, KEYENCE laser markers can mark a wide range of materials. These include materials such as metal, plastic, glass, ceramic, wood, and rubber. There are even more materials than listed that can be marked but some have been shown to emit harmful gases. In this event, proper guarding and fume extraction should be used to provide a safe operating environment.
When choosing the correct laser marking system for your business many factors should be taken into consideration. Throughout this process, you should evaluate all laser marking models to determine the proper wavelength, wattage, marking field of view, and safety requirements. Below are the main factors:
・Materials – this will narrow down laser marking models by wavelength.
・Time allowed for marking – with marking time you can determine wattage.
・Marking Style/Setup – whether it is a large logo or a matrix of small text this will determine the marking field of view.
・Integration style – safety is always a priority so inline vs offline solutions will change the safety requirements.
With KEYENCE having a large range of wavelength options to choose from, most materials have the ability when properly tested to be marked or etched. Some that do not properly absorb laser light or produce toxic fumes include Delrin, PVC, Glue Backing, and Foam.
In comparison to a conventional IR laser marking system, a UV laser marking system has a much shorter wavelength, typically 355nm, which gives it many advantages when marking specific materials and applications. UV light is the best option for laser marking objects made of heat-sensitive materials, such as plastics or resins. With the lower wavelength, you receive a higher absorption rate allowing for contrast marking on a wider range of materials as well.
When deep engraving with a laser marking system, any depth can be achieved depending on how much time is required to complete the mark. Depending on the material and level of depth laser marking may not be the most efficient solution.
