The Role Of Fiber Laser Protective Window

The base material of the laser protection lens/window is K9 or quartz material.
It is transparent, and it is made by grinding, polishing, coating and other
processes. It is mainly used to block debris from splashing during laser
cutting and avoid splashes from damaging the lens. Anti-reflection coatings
with high damage threshold (>15J/cm2) are coated on both sides to reduce
reflections.

The primary function of laser protection lenses is to protect the focused lens
and prevent spatter from splashing on the lens to cause damage to the lens.
Regular replacement and maintenance of the lens have to be conducted, so as to
ensure the accuracy of processing. It is required that the lens is coated with
a high damage threshold (> 15J/cm2) 1064nm anti-reflection coating, which can
effectively increase the laser transmittance, reduce energy loss, and improve
the quality of processed products.
