Bolt and Odin: Lens Selection and Comparison

Preface: This article covers the difference between the Four Lens options for the Odin series machines. The same principles apply to the Bolt as well.

Intro Video

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″
