The Four Lens Options Side by Side:
Engraving Test:
The same picture was engraved with all four lens with the same power speed with the picture parameters set as shown:
Speed: 1500mm/s
Power: 30%
Picture mode: Halftone
Cells per inch: 90
Comparisons:
1.5 inch lens:
The 1.5″ lens has the smallest burn dot to provide the most detailed engraving effect. But at the same time it has the shortest cutting thickness
2.0 inch lens:
The thickness of the 2.0″ lens cuts and the engraving effect are well balanced for most cases
2.5 inch lens:
The 2.5″ lens is ideal for thicker materials that require engraving and cutting
4.0 inch lens:
4.0″ lens engraving fidelity is not as good as other lenses but it is meant for cutting thicker materials
Dot Spacing Comparison:
When we have finished engraving all the images, we can then use a magnifying glass to compare the size of the burn dots engraved by each lens
Lens Selection based on Engraving and Cutting needs:
Fineness of engraving:
1.5″ better than 2.0″ better than 2.5″ better than 4. 0″
Depth of cut:
4.0″ better than 2.5″ better than 2.0″ better than 1.5″
