Different from manual or mechanical line aligning work, majority of engineers and professionals would prefer to operate a Berlinlasers 445nm blue line laser module for archaeology and artifacts. It applies a qualified optic lens within 10 to 110 degrees fan angles and different output power, which enables ultra fine, bright and clear blue line projection with various line lengths and freely adjusted laser line thickness. It makes clear line indication for artifact scanning and 3D construction, non contact and non destructive.
