Operating principle of LASER HEAD and Tube |
| As the CO2 laser is high power, so the laser head laser lens mount always get broken during long time usage, so it might sometimes be needed to replace the broken one. Laser head tube is a device for installing the focus lens. This laser head tube designed for different focal length |
| For an optical system in air, it is the distance over which initially collimated (parallel) rays are brought to a focus. A system with a shorter focal length has greater optical power than one with a long focal length; that is, it bends the rays more sharply, bringing them to a focus in a shorter distance.
The rule of thumb: The more delicate and detailed the graphics are, the smaller the lens should be chosen.For cutting thick materials, lenses of maximum size are recommended. For detailed information, please see the table below.
|
| Depth of focus / focal point |
| Depth of focus: The focal depth refers to the depth of the specimen layer which is in sharp focus at the same time. Depth of focus means the cutting thickness of cutting/marking.
Focal point: The point at which rays or waves meet after reflection or refraction, or the point from which diverging rays or waves appear to proceed. Focal point means the thickness of cutting/marking.
Longer focal length means bigger focal spot, longer depth of focus, but the mean power is lower. Shorter focal length is contrary. |
| Different Focal Length Means differnt cutting gap and cutting thickness |
| 1.5" laser lens (standard for laser engraving machine) <ENGRAVING> Graphics with fine detail, (resolution > 500 dpi), rubber stamps with thin letters <CUTTING> Lower laser power, thin materials (e. g. paper), acrylic< 6 mm, wood of medium hardness < 8 mm. 2" laser lens (standard for laser cutting machine, cutting thin material) <CUTTING>Increases the distance between laser head and material. Is especially useful if the increased distance is required due to the material and the graphic 2.5" laser lens (standard for laser cutting machine, cutting thick material) <CUTTING>High laser power, acrylic <12 mm, wood of medium hardness <15 mm focal distances 3" laser lens <CUTTING> 4" laser lens <CUTTING>Foam rubber 5" laser lens <CUTTING>High laser power, acrylic < 25 mm, wood of medium hardness < 20 mm focal distances |
