OPTICAL SETUP

The chosen focal length should create the smallest possible focused spot while providing the depth of
field required for the material to be processed. Optics are fragile and must be handled carefully, preferably
by the mounting ring only. Be careful to select optics that are thick enough to withstand the maximum
assist gas pressure available for the process. This is especially important in metal cutting applications using
high-pressure assist gases.
Cleanliness is another important issue affecting performance and becomes increasingly important as laser
power increases. Dirty or scratched lenses will underperform, exhibit a vastly shortened lifetime, and may
fail catastrophically.
When the application requires air (instead of nitrogen) as an assist gas, use only breathing quality air
available in cylinders from a welding supply company. Compressed shop air contains minute particles of
oil and other contaminants that will damage optical surfaces. If compressed shop air is the only choice
available, it must be filtered and dried to ISO 8573-1:2010 Class 1, 2, 1 specification shown in the table below.
