In order to get precise enough line alignment under all night version fields, it gets no manual labor force input and no mistake use of a 808nm infrared laser line generator. It is projecting invisible infrared laser beam, thus it should only be operating with night version device. Employing an import 808nm infrared laser diode within 100mW to 500mW, after correct equipment with 5V, 9V 1000mA DC power supply, it makes sure of high intensity infrared laser light emission, and highly clear infrared line alignment within 100 to 1000 meters in distance. The advanced use of glass coated lens makes good cooperation with a glass window. This 808nm infrared laser line generator is performing well, not affect by any moisture or dust as well. Available with wide fan angles of 10 to 110 degree, it should be selecting with correct optic lens degree and making proper adjustment of both laser line fineness and IR line projecting direction. Within freely installed distance of 3 meters, this infrared laser brings users no mistake and no barrier line alignment onto any raw material surface perfectly.
