Laser marker has become a popular tool amongst artists, designers, and entrepreneurs. With the help of this tool, they are able to turn bright ideas into actual drawings or designs on paper with amazing precision. This technology is fun to use and can lead to many creative projects! However, what no one is talking about is the intriguing psychology behind laser marker that makes it all possible.

The purpose of this blog post is to explore the science behind how laser markers work their magic on paper so you can figure out how lasers work for yourself.

The magic of laser marker

Laser markers are designed to use a laser beam to burn through the surface of paper. This technology is not new. It has been used in offices for decades. However, it has just recently become popular among artists, designers, and entrepreneurs who are looking to turn their imagination into reality by using this technology. How does this tool work? We will use the example of drawing an ‘S’ or a capital ‘T’. There are many ways you can make this happen with a laser marker. To make it simpler, I will focus on how you can draw an ‘S’ or ‘T’ on paper.

The distance between your marker and the paper is very important. If you are too close, you will burn through the paper! But if you are too far away, the laser beam will bounce off of the paper instead of burning through it. This is very frustrating! You need to find a distance where your laser beam can penetrate through the surface of the paper without burning through it. This distance in between your marker and paper is called ‘critical distance.’ The critical distance changes depending on how fast you move the laser in relation to the paper. If your speed is not fast enough, then your beam will not penetrate into the surface of the paper. It will bounce off of it instead. Again, this is very frustrating! You need to find the ‘just right’ speed for your laser marker to make it work properly.

Lasers are controlled using two optical lenses. These lenses are known as ‘diopter.’ The first diopter lens is called ‘intrinsic’ and the second diopter lens is called ‘extrinsic.’ The intrinsic diopter lens is responsible for focusing the laser beam on the paper. The extrinsic diopter lens controls how long the laser beam stays on paper. So when you are drawing an ‘S’ or ‘T,’ the intrinsic diopter lens will focus the beam on the paper just in time for the extrinsic diopter lens to control how fast your laser moves. You cannot have one without the other.

Your goal is to find ways to change both of these settings so that they are able to work together in unison so that your laser beam can penetrate through the surface of the paper without burning through it. There are many ways you can change these settings, but it depends on how you want to use them. So if you want more power when using your laser marker, then you should increase its intrinsic focus by changing its diopter setting with a screw driver.
