Ok i received all the basic items to start my RGY project.
I have a couple of questions about "pratical things".
I have a 650nm 300mW and a 532nm 300mW modules with analog blanking, a passing red reflecting green dichro, scanpro 20k galvos set, fb3 controller.
Now i will need to get an alluminium plate to set everithing, i think 1cm thickness is good but i dont know how large... any idea?
I'm planning to get enough space to add a blue module and make a RGB scanner in future.
Is easy to make holes in alluminium with a vertical drill?
And i have another question about my red module.
The beam is kinda thick (and slightly point towards bottom but i think theres no real problem cause i can collimate it using a mirror.), i will gladly reduce its diameter to make it pass easily inside the dichro mirror.
Is there a way to obtain a more concentrate beam?
The beam become more flat after some metres ( i think it's called astigmatism), can be a problem?
I dont have other questions for now
Thanks
