Within wide range work distances, the use of long wavelength device of 808nm infrared line laser alignment within 100mW to 400mW makes sure of highly precise and fine IR line generation for all night version illumination fields. Only after advanced use of 5V, 9V 1000mA DC power supply, and qualified glass coated lens and separate crystal lens within 10 to 110 degree, it assures highly straight and fine IR line projection. Only after its correct use of output power and optic lens degree, within freely installed distance of 3 meters, it brings users the lowest price and the most reliable IR line projection for military targeting, laser medical therapy, optical instrument, high tech and lab experiment work etc.
