A Simple Focal Test



Focus quality and cutting speed are critically dependent on the correct placement of the focal point relative to the material. Automatic machine parameters, which are programmed into the new lasers, usually make these minor vertical adjustments. The focal point may be moved 10-50 thousandths of an inch to provide the best cutting conditions. Occasionally the laser operator may also override the machine settings to “tweak” the focal point depth for better machine performance.

A focal test is a simple way to eliminate variation between lenses and improve laser performance. This simple test is often overlooked, but suppliers have a variation in their lenses. A focal test should be completed every time a lens is replaced.
