Which way should a laser lens be?
Lens Shapes A plano-convex lens should be oriented with the flat side toward the workpiece and the convex side toward the laser. Meniscus lenses have a concave curve on one side and a convex curve on the other.
How do you set the focus on a laser cutter?
If you want to make the focus be at the work piece then just adjust the Z axis down by the thickness of the material you were using. Then, just measure whatever you want to engrave and adjust back up by this thickness to be sure you are at the top of the material before processing.
What is laser focus lens?
A focus lens in a Co2 laser cutter/engraver converges the laser beam to create a focus point where the laser is cutting or engraving the material. This point is at the sharpest convergence of the beam, and is commonly referred to as the ‘spot size’.
How does laser focus work?
Laser auto-focus doesn’t rely on light from the object. Instead, it emits its own beam of light from which the distance to the object can then be determined. For this reason, the method will work in any lighting condition (it’s particularly beneficial for low-light photography).

What causes a laser lens to crack?
The temperature point at which the zinc selenide in the lens actually becomes less transmissive. As the lens continues to heat the zinc selenide passes less and less energy, overheating the lens until it cracks or shatters. Such lens “blow-ups” are not uncommon for most laser systems.
How do I get super focus?

Why is my co2 laser not cutting?
Causes for laser not cutting through The most common one is that the power of the laser is reduced or the lamp tube is aging, which makes the energy of the laser beam insufficient, resulting in the failure of the sample cutting through.
How do you laser a sharp focus?
What is the focal length of a CO2 laser?
BesCutter CO2 laser systems are typically equipped with one standard 2.5’’ focal lens for all the CO2 systems manufactured, but it can change depending on the application. The most common laser lenses are 1.5’’, 2’’, 2.5’’ and 4’’. All of the lenses are suitable for both cutting and engraving works.
What kind of lens do I need for a CO2 laser?
CO2 Lenses. CO2 laser systems are typically equipped with one particular focal lens – one that is generally good for most engraving and cutting applications. Epilog provides a standard two-inch focal length lens on all the CO2 systems we manufacture; however, we offer additional lenses that can help to improve specific applications.
What is a laser engraving focus?
The focus lens narrows or “focuses” the laser beam to a very small, precise spot that will enable graphic images to be engraved or cut with extremely accurate results. As the laser beam leaves the focus lens, it takes on an hourglass” shape, with the ideal focal distance within the center of the “hourglass..
What is the focusing lens of a laser cutter?
The focusing lens is an indispensable part of the laser machine, when you choose a focusing lens raw materials, diameter, focal length, and coating are the core factors In order to achieve high-quality engraving and precise cutting with your laser cutter, the laser beam is directed through a series of mirrors and through the focus lens.
