Hi all. I recently purchased an LT-4LDS-V2 by laser tree. The laser is 20w optical output which is plenty of power but the beam size I am getting is close to .2mmx.2mm which is a far cry from the .08mmx.08mm advertised. I work primarily with line art and often have lines that are close together but need to appear to be distinct, This does not happen with the larger beam size.
My question is… Are there any feasible methods of reducing the size of the beam that hits the wood? I was thinking like and aperture or series of lenses or is this a fools errand?
Using a ramp test and a digital microscope. I am sure I have it focussed properly. It is common for the diode laser companies to oversell them. There are four diodes in the laser so I think it struggles to get them small enough. I am unsure though as I am a complete novice.
It is flat flat flat baby. I am assuming that it is very difficult to do, otherwise you would imagine the companies making them would just do it. I am operating an Atomstack M50 at the moment and the beam size on it is the smallest I have experienced. It is really noticeable in tiny details.
