8-8 Special Applications Guide

Different lenses produce different spot sizes and have different focal ranges. For example, the

1.5” lens produces a spot size of .003” and has an effective focal range of +/- .075”. This lens

can engrave very fine detail but can only be used on very flat materials. On the opposite end,

the 4.0” lens has a spot size of .013” but has an effective focal range of +/- .2”. Although this

lens cannot engrave very fine detail, its focal range allows you to engrave on slightly rounded or

curved objects without the need for rotation. Using a baseball as an example, focus the beam

halfway between the highest point and the lowest point of engraving. Since a 4.0” lens has a

greater focal range than a shorter lens, you can engrave a considerable distance around the

ball without having to rotate it. Attempting to engrave further around the ball will result in a loss

of engraving power and a distorted image.

Refer to the following chart for spot sizes and focal ranges of the lenses available.

FOCAL LENGTH SPOT SIZE FOCAL RANGE

1.5 “ .003 “ + / - .075 “

2.0 “ .005 “ + / - .100 “

2.5 “ .007 “ + / - .125 “
