What is an easy job to make clear and fine enough cross line measurement? If it is processing at quite long work distance, it is operating easy and quick after the use of a 445nm blue cross laser alignment. It emits formal brightness blue laser light directly from 445nm blue laser diode. This direct diode emission made blue laser only adopts 16mm diameter, and also achieves increasing stability blue cross line source emission in continuous use. This blue cross laser alignment applies qualified glass coated lens, it emits the most complex two perpendicular blue lines with accurate 90 degrees. It is performing with high quality blue laser light source. Owing to its strict laser beam stability test and aging preventing test up to 24 hours, it is performing with good performance and no decay light blue cross line source emission in continuous use. When it selects correct output power and proper mounting onto industrial machine or device, it makes sure of high precision blue cross line source emission within the maximum work distance of 25 meters and formal lighting occasions perfectly.
