Whenever dot measuring work is processing with the highest level of accuracy and precision, it is just the best choice for users to try 532nm green dot laser diode module. Among all visible laser devices, it is emitting the most sensitive color and the brightest green laser light from middle wavelength of 532nm green DPSS laser system. Being made with the lowest laser beam divergence of less than 1mrad and good use of thermal emitting system inside its durable metal housing tube, this 532nm green laser enables the most convenient installation, and easy and highly clear green reference dot projection onto various working surfaces.
