The full-automatic diamond scriber is a standard in laser fabs across the world. It features a machine vision system and a diamond tip with motorized angle and a control mechanism for the applied force. It is the perfect choice for GaAs and InP substrates.
This laser scriber is probably the most used in the laser diode industry for up to 4″ GaN, sapphire or Si wafers. It is the best choice when the substrate does not have a cubic lattice structure since it does not depend on cracks but on thermal ablation.
