Red is still the show laser light source color that is most tricky to handle. As the power levels per single laser diode are rather low multiple diodes need to be combined to achieve higher power levels. To always deliver great quality we rely on Western European made diode array modules only.
Especially a professional knife edge combination of the single red laser diodes is decisive for an accurate beam profile - without losing too much power through optics!
The huge advantage of accurate laser diode array modules is that they can be used with small scanner mirrors and thus the inertia of these mirrors can be kept lower - resulting in faster scan speeds and better angle stability.
