Green laser: Sharp straight line pattern! Capable of projecting over long distances! [NETIS registered]

【NETIS Registration Number HK-240021-A】 Composed of a special filter that aligns the projection focus with the light source, battery, and the installation height and distance of the designed projector! This method is a technology that projects a light pattern onto the road surface, instantly visualizing the designated position of lane markings. It can be applied to sites requiring straight line marking work, such as road construction lane marking. Since marking work is no longer necessary, improvements in economy, process, safety, and workability are expected. 【Application Conditions】 ■ Natural Conditions: No restrictions due to wind ■ Site Conditions - Usable in environments with brightness below 200 lux (evening to early morning) - In daytime with brightness exceeding 200 lux, visibility of the pattern light decreases ■ Regions where technology can be provided: No restrictions on regions where technology can be provided 【Application Range】 ■ Applicable Range: Curves with a distance of less than 100m between the start and end points (BC to EC) of straight and curved roads ■ Particularly effective application range - Roads with long straight sections - Environments with low illumination such as night work or inside tunnels where marking lines are difficult to see ■ Inapplicable Range: Curves with a distance of 100m or more between the start and end points (BC to EC) *Please feel free to contact us.
