Default Which Dot Laser Can I Choose for Graph Paper

I am looking for a dot laser model, but get less experience.
I would like to know more details about the focus adjustment feature available in some laser models:
My request is as below:
1. Need narrow spot (2mm wide or close to) when projecting the laser beam to a target 5m far.
2. Laser dot is adjust focus to get narrow spots in a targets far from the laser over a 1m to 5m range.
3. Can I reduce the laser power to a human eye safe value like 1mW and still have a visible and focused spot in an indoor test room?
I need low powered dot laser module, output power and wavelength are not decided yet.
