Hi guys,
I'm new to lasers and wanted to ask for your advice.
I am looking for a fixed focus laser module, 5mw, 5v, 650nm, that would produce a very think, less then 0.5mm, line at a distance of 100 to 150mm.
So far I tired the cheap ~2$ fixed focus line laser modules that you can on get ebay, but their line was terrible, > 2.5mm wide.
I also tried the ~5$ adjustable focus modules, but was unable to get a good line at both 100 and 150mm distance.
I contacted a few manufacturers in China and they offered me a fixed focus laser that's supposed to give a think line at any distance <0.5m.
They are asking $9.5 for it ( I'm buying 1000 units, so the price is important ).
What do you think, is this price reasonable for the above specs?
