Adjustable Focus Lens Blue Laser Diode Module
What is an easy job to make highly clear dot measurement in distance? It is far more enough to reach with a simple blue laser pointer, but substituting by Berlinlasers 445nm blue laser diode module. It generates moderate brightness blue laser light directly from a 445nm blue laser diode, not as bright as 473nm blue DPSS laser system, this direct diode emission made laser device has just assured even more stable performance and much more compact size tube design.
This blue dot laser alignment gets high power up to 50mW to 100mW, which is only adopting 16mm diameter tube. It enables the mo
