In order to make precise enough cross line alignment under night version, not relying on manual work, it makes efficient job with a long wavelength made Berlinlasers 820nm infrared cross line laser module. It projects invisible infrared laser beam from a 820nm infrared laser diode. Only if it is working with night version device and getting proper use of 5V, 9V 1000mA DC power supply, it keeps work with continuous infrared laser beam emission and highly clear infrared vertical and horizontal lines at various work distances.
This 820nm infrared cross line laser module
applies qualified glass coated lens with different fan angles of 10, 15 and 110 degree. It passes through up to 24 hours aging preventing tests. Under operation with correct use of optic lens degree and proper adjustment of cross line fineness, this infrared laser gets increasing accuracy infrared cross line projection in distance. Users should just avoid operating without any eye exposure to beam aperture, it makes easy and stable IR cross line alignment for long lasting use.
Applications: laser medical therapy device, intelligence system, military targeting, scientific and lab experiment etc
