What are Laser Lenses and Mirrors?
In laser engraving or cutting, the results obtained depend largely on the type of lens used, in the same way that cameras use different lenses to take photographs.
The different lenses are differentiated by the focal length they provide, and is expressed in inches. The focal length is the distance from the lens to the focus of the laser. The decision of which lens to use depends on a series of factors: Laser power, type of material, detail, and resolution of the graphic (dpi) or the thickness of the material. As a general rule, it is considered that the greater the degree of graphic detail, the shorter the focal length of the laser engraving. The thicker the material you want to cut with a laser, the longer the focal length will be.
These lenses are made of Zn Se (Zinc Selenite), this material allows different special properties; such as greater light conduction, less heat absorption and greater resistance to pressure. Having a plane-convex structure, it generates uniform distribution of heat and power of the light beam.
Laser mirrors have a structure made of metallic molybdenum, this material allows greater refraction and prevents the mirror from being scratched.
A laser is a device designed to concentrate a beam of light at a specific point; It is made up of a pair of mirrors, an active medium that allows light to be amplified (in solid, gaseous or liquid state) and a beam of light or electric current that will give energy to the active medium.
