USA focal lens 18mm top quality

Choosing the right lens is extremely important.

Correct parameter and focus setting alone are not enough for the desired engraving.

Equally important is the choice of the right lens.

To choose the right lens, the following should be taken into account:

• Performance of the laser source
• Level of detail of the graphics
• Resolution (dpi)
• Type of material
• Material thickness

Rule for selecting the appropriate lens:

The more detailed and rich in analysis the plan,

the smaller (in terms of focus) the lens should be.

The thicker the material, the larger (in terms of focus) the lens should be.

Technical characteristics in simple terms:

Beam focus

The longer the focal length of the lens,

the larger the diameter of the beam.

The laser energy is focused by the lens

at a defined focal point.

The longer the focal length of the lens,

the larger is the surface on which it is applied

and the laser beam.
