UV lasers operate at 355 nm and are known as cold marking laser technology. The UV laser wavelength spectrum is highly absorbent by nearly all substrates. A minimal amount heat is transferred away from the marking area, making this marking solution perfect for sensitive plastics and metals requiring low heat stress. For example, sensitive electronics and circuit boards might require a UV mark to prevent damaging to surrounding circuits.
Our UV lasers operate by passing light through a crystal that filters out the 355 nm wavelength. The other wavelengths are then discarded into a third harmonic crystal (THC). During this process the THC increases in heat. Cooling the crystal is done by passing water next to it using a pump.
The laser system to the right contains the laser, computer, and pump. Our UV lasers are built for 25,000 hours of operation and are offered in static and flying variants.
The Automark UV lasers are offered in 3W, 5W, 10W, and 15W power options. All of our UV lasers carry a one-year warranty.
Our UV Lasers are offered in two configurations. The U series (Upright) and the O series (Open). The U series contains a window and reduces the Class IV laser to Class I laser specifications. The U and O series both have 300 mm work areas. All laser specifications are the same across our entire lineup. For larger parts, the O series is popular as it allows the full length of the part to be presented under the laser.
Our UV laser is suitable for metal materials and many nonmetals. It is widely used in electronic components, integrated circuits, hardware, automobile parts, plastic products, and is especially useful for high quality laser precision micro-processing. UV lasers can mark glass, diamonds, sapphires, LCD panels, IC grains, polymer films, ceramics, polypropylene, PA, and other thermoplastics. To see if we can mark your part, feel free to reach out to us as we offer free ink adhesion tests.
Our AMUV-E line of UV lasers are tightly integrated, containing the entire laser source, control hardware, computer system, and chiller in one nicely integrated package. The entire system is covered under the same warranty. This integration allows for plug and play operation right out of the box.
Lasers are regulated by the FDA due to the radiation they emit and they are classified based on the damage they can do to skin and eyes. A Class I laser is a laser that is totally enclosed with no way for the beam to escape. This is similar to a laser desktop printer and cannot cause eye or skin damage with normal use.
A Class IV laser is the highest classification of laser, meaning they can cause significant skin and eye damage, and Class IV lasers can cause damage even if viewed indirectly. Our lasers, when operated properly, are extremely safe.
Operator safety is paramount, so we offer an entire line of lasers that transform a Class IV laser into a Class I laser by enclosing it in a sealed unit. This is the E line of UV lasers.

With a beam diameter nearly 70% smaller than a comparable fiber marking system, our UV laser systems offer high precision marking with no thermal effect to the surrounding area. Combined with low power consumption, customers can mark on a wider range of substrates – without damaging them – while maintaining very low operating costs.
Standard lasers have a focal point with a tolerance based on the distance from the lens. This varies depending on the lens size selected. The focal height is only a few millimeters. A round part is challenging for two reasons. The first reason is the distance is changing as the slope of the Z-axis declines around the part. The second reason is because the center point of the galvanometer is creating a “longer” traverse to create the same image. This means that if a person was to use a standard, 2D laser to mark a round part, they may get elongated markings as the beam trails off over the edges.
To counter this, we can use two separate systems, independently or together:
We can use a rotary to hook the part onto and spin the part. The rotary feeds information into the laser, so the laser knows where it needs to mark. This is done if anything greater than 120-degree printing is required. Smaller rotaries, like 50mm, are perfect for rings and small items, whereas the larger 100mm rotaries are perfect for mugs and firearms.
A second way is to use a 3D laser system. This is a laser specifically built that dynamically changes the focal point inside the system. This provides the ability to print from 60- to 100-degrees on the part.
We offer flying laser solutions for moving parts like bottling operations, assembly lines, and conveyor-belt part marking. Special photography can be implemented to identify part orientation so fixtureless printing is enabled. For details on this and other customized solutions, contact us to discuss your program in detail.
