On consideration of low price and high stability dot measurement, either it is pointing at close or long distance, it makes good job with a Berlinlasers 650nm red laser diode module within 5mW to 100mW. It projects highly visible red laser beam emission from a 650nm red laser diode. Being made with good cooling system and different diameter tube, it assures good thermal emitting and highly stable red dot projection in long lasting use.
Being made with highly durable anodized aluminum alloy housing tube, this red dot laser alignment is applying for wide operating temperature and other harsh occasion etc. The advanced use of APC, ACC driving circuit board assures the most reliable red dot projection, and no effect by overheating and over current impact as well. Within long lasting time of 8 to 10 hours, it provides users the most reliable dot alignment for industrial and high tech fields, including drilling system, laser marking, laser engraving etc.
