When dot measuring work is processing at various work distances and lighting occasions, it makes good job after the use of Berlinlasers 532nm green laser diode module. Available with wide range output power of 5mW to 100mW, being made with metal heat sink cooling system and durable metal housing tube, after proper use of 16mm and 26mm diameter tube, this green dot laser achieves good thermal emitting, and increasing accuracy and stability green dot projecting in long time use. The basic use of glass coated lens assures high transmittance green laser light emission, and highly clear green dot alignment at various work distances. Owing to its strict laser beam stability tests and proper use of glass window in front of beam aperture, this green laser diode module is performing with highly clear and accurate red dot projection, and also getting no affect by any moisture or dust etc. When it makes proper mounting onto industrial machine or device, within the maximum distance of 25 meters, it makes high accuracy dot alignment in all occasions effectively. Technical data: Item: Berlinlasers 532nm green laser diode module Output power: 5mW-100mW Laser class: IIIa, IIIb Optic lens: glass coated lens Adjustable focus: yes Power source: 5V, 9V 1000mA DC power supply Applications: drilling system, laser marking, laser engraving, military targeting and lab experiment etc
