What is a good job to make clear and precise line indication for various scientific research works, not relying on any prior line drawing or printing, a lot of engineers and professionals to apply a Berlinlasers 445nm blue line laser module. Employed by an import 445nm blue laser diode and a qualified glass coated lens within 10 to 110 degree fan angles inside a different dimension metal housing tube, it gets high linear quality and highly straight blue reference line projection within 0.5 meter to 6 meters length in use.

After properly adjusted laser line thickness and line emitting direction, a correct output power and optic lens fan angle made blue laser line generator enables good line alignment results for all scientific research fields conveniently. This accessory part provides ideal line alignment source for optical experiments and beam characterization, fluorescence excitation and spectroscopic analysis, 3D scanning principle verification, and material surface analysis works etc.
