When selecting a laser, focal length and diameter are the most important parameters to consider. These two parameters determine the power density of the beam and the focus distance, or the distance between the lens and the material being analyzed. For CO2 lasers, the larger the diameter, the greater the power density. This is because the beam expands to fill the larger focal length. The deeper the spot, the less intense the light, the shorter the focal length. A specified focal-length is a compromise between the desired spot size and the depth of penetration, and is usually required for workpiece clearance.
Selecting a laser lens:
The second factor to consider is focus tolerance. A larger lens has a wider focus tolerance, which is ideal for cutting thick materials. On the other hand, a smaller focal-length will result in a smaller focal-spot, causing the laser beam to converge faster and create a shallower depth of focus. This results in an image with sharper details. Therefore, the larger the field of view, the larger the lens's focal-length.
Features of a laser lens:
When choosing a laser lens, a focal-length of 60 mm is appropriate for most applications. However, if the target surface is more narrow than the focal plane, a longer focal-length will be necessary. The smaller the focal-length, the more precise the marking will be. With a smaller focal-length, you can also use a higher-power CO2 laser to mark bare metals. With a 0.060-inch-thick lens, the energy density is sufficient for direct marking of bare metals with CO2 laser.
The focal-length of a laser lens determines the focus distance. The focal-length of a laser lens varies between different wavelengths. The shortest wavelength produces the widest spot while the longest is closest to the surface of the workpiece. A smaller diameter means less focus. A longer one has a shallower depth of focus, which makes it less efficient for welding. This makes for a longer working distance. If the focused spot is narrower than the focal-length, it is likely to be the better choice.
CO2 laser systems typically come with one focal lens. A one-inch-long lens is good for most engraving and cutting applications. High-quality lenses should be used for high-resolution raster engraving. A four-inch-long-focal lens for a CO2 laser system is recommended for optimum performance. A five-inch-long slit will yield the best results. When using a two-inch-wide focal lens, you should aim for the lowest DPI.
Aspects of laser lens:
Another aspect of a laser lens that is often considered to be undesirable is its focal length. While this may not seem important, it can affect the accuracy of a laser. This can lead to poor quality and inaccuracy. If you need a long-focal laser lens, you'll need to adjust your machine's height to compensate for the extra distance. For machines with shallow focus depth, you can purchase a modified nozzle.
A high-quality CO2 lens is vital for optimal results when using a laser. A high-quality lens should have a smaller focal spot than a lower-power laser. It will make your cutting process more accurate. A small laser lens will also allow you to make more precise marks. If you're using a CO2 gas laser, consider the focal-length of the lens. The larger the spot, the higher the energy.
Design of laser lens:
Endurance laser lenses are designed with 3 elements: the G2 and the G8. The third element is the XL. The endurance laser lens will be able to transmit visible light. It is essential to choose a lens that's designed for your application. You can get a custom lens at an affordable price from a manufacturer. These are the best options for your applications and they'll save you a lot of money in the long run.
The laser's power is a key feature for improving the quality of a lens's focus. A lens that doesn't focus can make the light of a laser beam less effective. When it focuses, the beam's focus is improved. The lens also helps to correct a lens's alignment. A proper focusing and collimation are crucial to improve the quality of the beam. If you're looking to buy a laser-optical device, you can be sure it's worth the investment.
