The Raptor laser marker employs a new technology – Enhanced Fibre (EF) Technology - which gives the user a full four-year warranty.
Raptor is a compact new laser marking system with a very small laser enclosure, incorporating an optical unit fully sealed to IP67, to ensure low maintenance even in hostile environments. An annual health check is normally all that would be required. The system is entirely air cooled, eliminating the need for water or refrigerant circuits and takes power direct from a single phase socket outlet. Raptor is supplied as a modular unit for production line integration but can equally be supplied with a safety workstation as a turnkey solution. The 5U, 19” rack electronics enclosure is about the same size as a tower PC. Raptor is equally proficient in high and low volume applications.
EF Technology provides very short energy pulses - 25 ns compared with anything from 70 ns to 200 ns in other systems. This enables high peak powers (up to 10 kW) to be combined with low pulse energies and this facilitates high contrast, low damage marking on metals and plastics. The highly controllable beam virtually eliminates surface damage around the mark and to delicate substrates, enabling EF Technology to be used for marking components where surface finish and retention of material integrity are paramount, especially in demanding telecommunications and automotive applications.
Near perfect beam quality and exceptional energy stability over the entire operational range mean E F Technology delivers very small spots, typically 70 µm from a 254 mm lens. Smaller spots are possible (down to 25 µm) with high speed, self tuning Digital Signal Process (DSP) galvos. This creates high energy intensities to give a substantially improved performance compared with more traditional systems. The high beam quality facilitates large depths of focus, so laser markers built on E F Technology are better able to mark complex, curved or awkwardly shaped components. There is no ramping in or out of the power and pulse frequencies range from 0.1 to 100 kHz. The temporal pulse pattern permits bit maps etc to be marked easily and with high definition.
