There are four (4) common laser focal lens available.

Lens = Dot diameter
1.5" = .003"
2.0" = .005"
2.5" = .007"
4.0" = .012"

Each one of the lens serves a purpose.

1.5" lens with such a tiny dot diameter size lends itself for very tiny to small images that require high detail. The Italian Charm Bracelets lend themselves well to this lens. As good as the dot size is for detail the cutting ability is terrible as it can only effectively cut standard engraving plastic stock and thinner, not much else.

2.0" lens straddles the fence for great engraving quality due to the reasonably small dot size and the cutting ability of this lens is good enough to allow enough continuous power after the lens distance to continue on to cut rather well, even up to 1/2" to 5/8" thick acrylic.

2.5" lens straddles the fence for really good engraving quality due to the reasonably small dot size and the cutting ability allows for enough continuous power after the lens distance to continue on to cut extremely well, even up to 5/8" to 3/4" thick acrylics.

4.0" lens is extremely good for cutting ability as after the 4" focal distance the lens maintains enough continuous power for greater distance than the other 3 lens making for a great cutting lens, especially for thick materials, such as 1/2", 3/4", 1" thick acrylics.

Listen in as the details are explained as to why each can engrave, cut or engrave and cut.
