Coders from other companies, in general and by comparison, has a single laser tube that must be exchanged by specialised service personnel. When their laser fails, the marking stops until the service technician arrives and a replacement laser tube is installed. As with most electronic components today, miniaturisation is the key to the future. Domino leads the laser community in the miniaturisation of gas laser technology. By distributing the power load over seven sources, the lasers can be made as small as possible.
Small size leads to laser stability and mass reproducibility.
Other laser companies don't have access to the technical advances present in the DDC3 laser tubes and thus they can't reproduce the miniature DDC3 tube. By distributing the laser power over seven lasers, the entire power of the DDC3 laser system can never hit one spot. With a high-power single laser beam used by other companies, the energy from the laser is concentrated at a single spot and is potentially more hazardous.
