Laser Engraving Mirror: the Ultimate Guide 

Simple mirrors can be turned into eye-catching pieces through laser engraving. It is possible to make any design, engrave a photo, write special words and dates, and personalize it as you like. It just amplifies the elegance of the mirror and gives it a unique and personal touch. You can use it as a mirror, décor piece, or gift item.

A laser engraving machine can remove the coating behind the mirror. This is the reflective coating of aluminum or silver that reflects the light. Any design or image can be created by removing the coating of the mirror, and the area from where the coating is removed acts like transparent glass. It can backlit using lights and make it more attractive.

Let’s see what types of laser machines you can use and the step-by-step guide for laser engraving mirrors.

Can You Laser Engrave the Front of a Mirror?  

Yes, it is possible to engrave the front of a mirror, but it will be a bit different in texture, appearance, and engraving phenomenon. 

When you engrave a mirror from the back, the reflective coating of the mirror is removed. There is no effect on the glass, so you don’t see any frosting. Light can easily pass through this engraved surface because it acts like transparent glass. It can also be called laser etching.

On the other hand, when you use a laser machine on the front of a mirror, the glass is engraved. The laser beams create minute cracks that give a frosted appearance to the glass.

For engraving the front of the mirror, the ideal option is a CO2 laser. It can directly engrave the front surface. If you are using a diode laser, you need to use laser marking paper or a coat of paint. Do not use toxic things like galvanizing spray.

Types of Lasers That Can Be Used for Engraving Mirrors 

CO2 Laser 

A CO2 laser is the best option for engraving mirrors. These laser machines can easily process both sides of a mirror and offer incredible results. The wavelength of the laser beams emitted by the laser is around 10,600nm, which is an ideal option for glass and mirrors. This wavelength can be easily absorbed by the material. There is no need to apply a coating or anything else at the front surface for engraving, and the back can also be engraved without any hassle.

Diode Laser 

Diode lasers can also engrave mirrors. For engraving the back side, you can start the process right away. However, for engraving the front side, you need to use laser marking paper or anything else that can absorb the laser beams. Otherwise, the beams will pass through the glass and reflect back, and nothing will happen.

Engraving a mirror using a laser machine is pretty simple. You only have to follow a few simple steps and keep some important aspects in mind, such as the inversion of the image. However, you may need to try several times to get the optimal power and speed settings.

Step 1: You need a piece of mirror according to your desired size. Clean the mirror from both sides and remove dirt and grease.

Step 2: Prepare the design that you want to engrave on the mirror. You can either get free or premium designs from websites or create your own if you know how to design and use software like Adobe Illustrator.

Step 3: Turn on the laser machine and connect it to your computer. Open the laser software and import the graphics file you want to engrave. If you are engraving at the back of the mirror, make sure to horizontally reflect the image or graphics. Otherwise, you will have an inverted image.

Step 4: Set the power and speed for engraving. There is no hard and fast rule for selecting these settings. You will have to try a few times or run a power-speed test to get the optimal values. We are using a 10W diode laser machine, and we get optimal results at 28% power and 75 mm/s speed. It can be done in only one pass.

Step 5: Place the mirror in the working area. Make sure the coated surface is facing the laser module. Now, start framing to get an idea of the position of the graphics. Adjust the position or size if required. Finally, click on the Start button and let the machine complete its job.

Step 6: After engraving, you need to clean the mirror again to remove the coating. You can use soap and water. Your laser engraved mirror is ready. Now, you need to make it more attractive by adding lights at the back or securing the mirror in a frame.

Conclusion

Mirror engraving is one of the latest trends because it makes a simple mirror alluring and eye-catching. Laser enthusiasts would love to try this using their laser machines. We have shared the step-by-step procedure, explained how laser engraving mirror work, and which machines can engrave a mirror. It is a complete guide that will help you make astonishing mirror pieces with minimal effort.
