Abstract
A cross line laser (100) comprises a shell and a hanging system (101). The hanging system has two laser modules (110) arranged oppositely on a same plane. Each laser module comprises a laser device (121), a collimation device (130), and a cylindrical lens (140). The cylindrical lens has a high refraction index. Lasers emitted by the laser device passes through the collimation device and are incident on the cylindrical lens, and are split by the cylindrical lens to form laser rays with a diffusion angle approximately larger than 180 degrees. Horizontal laser rays generated by the two laser modules intersect with each other, so as to form laser rays with a diffusion angle of 360 degrees.
