How to get a low price 650nm red laser diode module correctly?

When you are looking for a low price and high precision dot alignment solution for all machinery processing work fields, either it is pointing at close or long distance, it makes good job for users to operate a high intensity beam device of Berlinlasers 650nm red laser diode module. Employed by an import red laser diode and cooling system, cooperating with different dimension and durable metal housing tube, it assures easy installation and highly reliable red dot indication in long lasting use.
This 650nm red laser diode module applies a qualified glass coated lens and glass window inside durable metal housing tube. It also passes through up to 24 hours beam stability tests, thus it achieves highly reliable and no decay light red dot emission in constant use. After its proper mounting onto industrial device and freely adjusted red dot diameter, it achieves high concentration red laser light emission and high level of accuracy red dot alignment at various work distances perfectly.
Applications: drilling system, laser marking, laser engraving, red laser sight, military targeting and high tech etc
