Maybe i found a much cheaper way for a "flat field lens". I try to simulate (with WinLense) a Lense Array out of three lenses. I think it can work and give the precission i need for less than 200$.

Hey, I find the so called "f-theta" lense today. This seems to be the sollution for my problem. But more then 1000€ (edmund) for a lense is extreme over my budget. Small Picture of my Build: The focus lense alias "Magic Lense" is my problem. The distance between the mirror and pcb can i adjust...

Thx for the links, i will try to understand and calculate the lenses i need. But its not so easy for a beginner in Gauß Optics ;)

The alignment is no problem. I have a big Al Block to mount all things on. Lense size are ok if they are smaller than ~50mm.

This is a problem... The distance difference between the (pcb) border to the mirror and (pcb) center to the mirror are to big, when the space between pcb amd mirror is to small. (Sry hope you understand what i tried to explain) Edit: I recalculate a bit: maybe 15cm beam length is enough.

Hey, im new and have some questions to the professionals here ;) Im building a Laser Exposer for PCB's, i use a old laser printer polygon mirror to control my beam. The laser diode is a "BDR S06J 12x" at ~350mA. My main problem is now to focus this beam to a size smaller then 100µm (0.1mm)...
