Top-quality USA focal lens 20mm
Choosing the right lens is extremely important.
Correct parameter and focus settings alone are not enough to achieve the desired engraving.
Choosing the right lens plays an equally important role.
To choose the right lens, the following must be considered:
- Laser source output
- Level of detail in the graphics
- Resolution (dpi)
- Material type
- Material thickness
Rule for choosing the right lens:
The more detailed and higher-resolution the design,
the shorter (in terms of focal length) the lens should be.
The thicker the material, the longer (in terms of focal length) the lens should be.
Technical specifications in plain terms:
Beam focus
The longer the focal length of the lens,
the larger the beam diameter.
The laser energy is concentrated by the lens
at a defined focal point.
The longer the focal length of the lens,
the larger the area over which it is applied
and the laser beam.
