Facts You May Not Know About Laser Engravers
It was back in the 1960s that scientists working with light made the actual discoveries that led to the development of modern-day laser engravers. They discovered that light generated from certain gases, when focus into a beam could be used as a tool.
A High Energy Light Beam
So why then can’t you simply focus the light from a standard light bulb into a laser beam? The problem there is that the light is of varying wavelengths, which makes it far too difficult to focus. Also, light that is used to create laser beams for laser engravers require a lot of energy to create.
Passing Electricity Through Enclosed Gas
CO2 gas is used to create the light source for laser engravers. It’s basically done the same way that light is created from a neon light bulb, only it’s CO2 gas that is contained in the bulb. When electricity is passed through the CO2 gas its molecules are agitated and the light is produced. More electricity results in a higher rate of agitation. Thus; a higher energy laser beam.
Laser Engravers Can Engrave On Anything
So what are the actual benefits of laser engravers when compared to more conventional engraving methods? Actually, they are many. To begin with, laser engravers can engrave on almost any type of material. On the the other hand engraving methods that require chemicals or a blade can be limiting with regards to materials that can function on.
A Far Cleaner Method For Engraving
Another big benefit of laser engravers is that they generate no residue or dust. This means that they can be used in virtually any environment, including sterile manufacturing environments. Laser engravers also easily engrave on surfaces of any shape, unlike other standard engraving methods that for the most part require a flat surface.
