Choosing the Best Laser Engraver for Glass: A Complete Guide
Glass is everywhere. From the windows in your home to the ones in your car. From the mirror in your washroom to the plates you eat in, wouldn’t it be wonderful to make the glass you own permanently?
To make them look different from all the other similar pieces out there, and etch something that’s your “own” onto them? That’s easily possible by engraving them. While classically, a lot of methods have been used to engrave glass, they normally require experts and highly expensive equipment.
Laser changes that. It brings the power of engraving whatever you want, however you want, to your hands. While this technology is used by businesses and the corporate sector alike, it’s accessible to the general public and amateur enthusiasts as well.
However, due to their immense popularity, a lot of companies and startups have emerged onto the scene, each claiming to manufacture the best laser.
It’s important for everyone to be aware of the basics regarding how laser engraving on glass works and to differentiate a good laser engraver from a bad one.
How Does Laser Engraving for Glass Work?
The basic premise behind a laser engraver is that the laser beam focuses different wavelengths onto one tiny point. While the waves aren’t powerful when separate, when combined and focused on one point, they become a force to reckon with.
This focused, powerful beam removes small particles from the glass surface, which results in a permanent image or design being etched onto the surface. The benefits of using this technique are that the details are precise down to the dot, and the results are permanent.
What type of laser engraver can engrave glass?
Usually, there are two kinds of lasers used for this purpose: CO2 lasers and diode lasers. The main difference is that CO2 lasers are stronger and result in deeper engraving on thicker glass while consuming more power.
Can CO2 lasers engrave glass?
Yes, CO2 Laser Engravers are renowned for their high power capabilities, making them suitable for engraving thicker glass and producing intricate designs with precision. However, they often come with higher maintenance and power supply costs and require ventilation due to the production of fumes when engraving glass.
Can Diode lasers engrave glass?
In contrast, Diode Laser Engravers typically have lower power compared to CO2 lasers but are still capable of engraving most types of glass. They are more portable and compact, consume less power, and may require lower maintenance. Moreover, they can be more cost-effective for lighter engraving applications on glass.

Critical Considerations While Choosing the Right Laser for Glass Engraving
While there certainly are a lot of reasons to choose one laser over the other, we will list down a few of the most important characteristics you should consider when selecting a laser for your glass engraving project.
Power Output
Similarly, just as you must weigh the trade-offs between power and power efficiency when selecting the type of laser, you also need to consider your priorities based on your specific project requirements. Opting for a laser with higher power output might offer greater engraving capabilities but could result in increased energy consumption.
Conversely, prioritizing power efficiency may limit your engraving depth but could save on operating costs. At OMTech, we understand the diverse needs of our customers, which is why we offer a range of glass laser engraving options tailored to different power levels.
Ease of Use
One important yet often overlooked characteristic is the ease of use of a laser. While lasers to engrave glass were all almost uniform in terms of their accessibility, recently, they come with control panels.
Excellent lasers such as OMTech Laser come with state-of-the-art control panels and readily available software for design creation, which can make the process effortlessly simple.
Safety Features
If there’s one thing on the list to not sacrifice, it’s safety. A laser with proper safety features can be the difference between a successful project and a disaster. Always opt for lasers that are reputed and have built-in safety features such as emergency stop buttons and interlocks.
