Accessory Part of 808nm Infrared Laser Diode Module In those of night version precise dot measuring work fields, not easy to reach with any visible laser device, it makes even better job with a long wavelength made Berlinlasers 808nm infrared laser diode module within 100mW to 400mW. It is projecting the most intense and powerful infrared laser light directly from a 808nm infrared laser diode. The advanced use of qualified glass coated lens and glass widow are configured with metal housing tube. It is working well with high transmittance infrared laser light emission and highly clear infrared dot alignment in distance. This infrared laser diode module adopts external AC/DC adapter, not relying on any manual labor force input, it keeps work with the most intense infrared laser light emission, and highly clear infrared dot alignment within long extending distance of 100 to 1000 meters. After its easy adjustment of laser beam focus and dot emitting direction, this infrared dot laser makes no mistake and no barrier dot alignment for all night version fields constantly. https://www.berlinlasers.com/808nm-infra...er-diode-module
