Elongated Focus with uniform intensity

 Our  DeepCleave module focuses an incident single mode laser into  a  tight spot with  ~ 1.8 um waist size along the  entire Depth of Focus range (1-2mm typical range) .

The focused spot is equivalent to 0.35 objective NA and is ideally suited for glass cutting of thick glasses, such as flat panels. 

This module is a complete optical solution for cutting applications. No need  for additional high NA objectives or other high cost  optics. 

The DeepCleave module differs from standard EF elements by constant peak power along the focus region and requires  low M^2 and accurate  input beam size.
