When red laser module is equipped with qualified line emitting lens, such as glass cylindrical lens or separate crystal lens, it forms into an industrial stabilized red laser line pointer. According to the configuration of wide laser lens degree of 10 to 110 degree, this laser line module generates different laser beam fan angle, forming into various line length and line thickness in distance. It is also accepting customized manufacturing, which can fulfill the most precise line alignment and measurement in all precise device manufacturing works efficiently.
