An apparatus for laser scribing two transparent electrically conductive layers (72A,B; 73A,B) deposited on opposite surfaces of a transparent substrate (71A; 71B) comprising; a laser beam (74A), one or more lenses (75A, 76A, 77A) configured and positioned for adjusting the focal spot (78A; 78B) of the laser beam between a first position (78A) and a second position (78B), means for holding a substrate in a plane between the first and second position and means for moving the relative positions of the substrate (71A; 71B) and laser beam (74A) in two dimensions within the plane or a plane parallel to it, wherein in use, the first and second positions (78A; 78B) coincide with or are adjacent to exposed surfaces of the two transparent electrically conducting layers (72A,B; 73A,B). |
