What is the best job for users to make highly clear dot alignment? It might not be easy to reach with a simple green laser pointer. However, after the use of a 532nm green laser diode module and 5V, 9V 1000mA AC/DC adapter, it keeps work with the most visible green laser light emission and the clearest green dot alignment at various work distances. 
The special use of a qualified glass coated lens is configured with highly durable anodized aluminum alloy housing tube, after proper use of 16mm and 26mm diameter tube, this green laser diode module ensures good thermal emitting and highly stable dot alignment within wide range operating temperature. In occasion that it makes correct use of output power and easy installation, without any barrier of long distance or high height, it assures low cost, high stability dot generation for all precise device manufacturing work fields effectively.
