Hello everybody,
I'm French and I recently bought a Green laser pointer 5mW from 'ChangChun New Industries' (China). At first blush all seems to work good, but after few minutes I found a big beam divergence ! Between 1 and 60 cm the laser dot diameter is approximately 1mm, but after 4m, it is 1.5cm !!! Is this normal ? I think that it isn't normal, The problem certainly is the collimating lens glued on the laser head...
I can easly remove or move the lens on the laser head, but I don't know if it is a good thing ? I need your advices !... Many Thanks to all, Seb
