If users are not much sure of how to make ultra clear dot indication at long work distance, it just makes a good job with a Berlinlasers 50mW to 100mW blue dot laser alignment. Being made with an import 445nm blue laser diode inside 16mm diameter metal housing tube, after passing through up to 24 hours beam stability test and aging preventing test, it achieves high density blue laser light emission and ultra clear blue dot projection at long extending distance constantly.
After quite easy connects with 5V, 9V 1000mA DC power supply, this alignment laser makes high speed and quick response blue laser beam and blue dot projection at long extending distance. It gets no need to rely on any manual labor force input. Any time it makes correct use of output power and proper adjustment of laser dot diameter, within the maximum work distance of 25 meters, it brings users the best direction and the longest lasting dot indication for all machinery processing works effectively. 
Applications: industrial device manufacturing, laser show, laser displaying, laser communication, optical instrument and high tech

Whatever kind of working surface users are in serious need of ultra clear and fine line indication for all night version illumination work fields, it is not able to rely on any visible laser device or any other formal manual line drawing tool at all. At the same time, under constant technical innovation of advanced 808nm infrared laser diode tech, it is created into a quite practically used night version device of a 808nm infrared line laser module. It emits uniform and fine infrared reference line from laser beam aperture. When ultra compact size tube made IR laser line generator gets proper installation and adjustment to correct position, it brings users the easiest reaching and the most precise infrared line alignment at long extending distance effectively. 
The advanced use of a uniform beam 808nm infrared line laser module is in need to work for a quite long time, thus it is a major part to maintain its stable performance in long lasting use. Cooperating with a metal heat sink cooling system inside a durable anodized aluminum alloy housing tube, being made with 16mm and 26mm diameter metal housing tube, this direct diode emission made infrared laser line generator has just achieved superior nice thermal emitting and thermal conductivity. It enables constant infrared line alignment within daily operating time of 8 to 10 hours, without any worrying about laser light decay or dim in continuous use. 
According to its easy connects with AC/DC adapter, accepting wide range electric current of 100V to 240V, this uniform beam 808nm infrared line laser module enables long lasting infrared laser beam and infrared reference line projection. It generates non Gaussian distribution IR laser light source, and ultra fine IR line. It keeps work with the same line brightness from its middle part towards both ends, as a result, once infrared laser line generator is used at quite long work distance of more than 50 meters, it still assures its ultra high fineness and high straightness infrared line generation in long lasting use.
Within quite long extending distance and quite long time constant infrared line generation work, this uniform beam 808nm infrared line laser module is working well as an accessory part, which is also making excellent infrared line indication for infrared laser sight, IR laser communication, laser medical therapy, military targeting and lab experiment work etc. It brings users the best measuring experience for all precise machinery processing works. For the most important of all, any time infrared alignment laser is applied for all night version fields, users should wear infrared laser safety goggles and avoid eye exposure to laser beam aperture so as to achieve easy, free and secured effectively. 

Different from any other visible laser devices, in order to get ideal dot alignment accuracy for all night version fields, it should be a good choice to operate a long wavelength made device of Berlinlasers 808nm infrared laser diode module. Employed by an import 808nm infrared laser diode inside 16mm and 26mm diameter metal housing tube, after getting superior nice thermal emitting, it achieves ultra stable and reliable infrared dot projection in continuous use.
Cooperating with a qualified glass coated lens and glass window inside, the genuine use of a IR laser diode module achieves high transmittance IR laser light source emission, ultra clear and precise infrared dot alignment as long as 50 meters. It should only be selected with correct output power, within freely installed distance of 3 meters, it brings users the best direction and the longest lasting IR dot alignment for all night version fields effectively.
Applications: infrared laser communication,optical instrument, military targeting, laser medical therapy and high tech etc
