I use YLF DPSS lasers for an industrial marking application. I need to mark alphanumeric serial numbers in an OCR-able font. The machines I have now, are so ancient that I can't buy galvos or get them repaired, plus they operate slowly and the controller software is very limited.

I'd like to rip out the current X-Y galvos and controller computer and replace it with a new scanning head and controller. I'm having a hard time shopping for this sort of thing, though. The only vendor that I've come up with is Cambridge Scanning; they have some scan heads that will work but the only controllers they have are limited in terms of interface. Are there other companies that sell X-Y scanning optics and controllers? A controller that is specifically for marking text would be great but I can program the actual marking software to do whatever.
