The mira series is perfect for objects typically up to ½” thick and smaller in size, and these lasers have superior engraving and shading quality, with the power range being limited to 100W.
Laser power options start at 30W, which are available in CO2 (glass laser tube) and RF (metal radio frequency tube). The options for the Mira series range from 30W – 100W, and the reason for this range effect is that the 30W-75W is ideal for fine engraving and tends to have a thinner kerf.
The Nova series laser starts with 75W of power, which will still provide excellent engraving detail, but as you increase your power, the item you are engraving should also increase in size to maintain a sharp appearance. The 75W+ laser tubes make quick work of cutting any material with great detail and are perfect for nesting applications or large material cuts with a thickness typically up to 1”.
