Hello Everyone
I am studying on Galvolaser for my university finishing project. I find mirrors and f theta lens for 1060 nm but 1060 nm laser module is really expensive and ı never buy it. I can use 450 nm laser module but ı couldn't find the appropriate mirror and lens. So I have to prove can I use or can not use 450 nm laser with 1060 nm's mirrors product. How can I prove it ?
... dielectric coated mirrors for 1064nm are mostly transparent for 450/455nm - so better use silver coated mirrors.
The f-theta lens for 1064nm will create much reflections inside, so you'll loose some power and receive some mirrored "satellite" spots - if you can't find f-theta for 445nm, then you can use 532nm types ... some satellite reflections too, but not this strong as with 1064nm lenses ...

Could you offer me suitable product lasermodule mirror and lens from aliexpress or like cheap sites. Actually I havent't much ideas. I need help
... f-theta for 532nm or 455nm are not this common, so even more expensive than 1064nm ones :(
Silver coated mirrors can be found cheap - search for the cheapish Chinese galvoscanners -- they mostly have silver-coated mirrors, which too are available as spare for repair ...
