A laser beam focusing lens having a partially reflective coating layer

摘要

The present invention relates to a focusing lens of a laser beam having a reflective coating layer for improving the viewing angle of the laser radar by coating a partial reflecting layer on the focusing lens of the laser beam. The present invention relates to a focusing lens for focusing a laser beam on one surface and a convex surface on one surface, wherein a partial reflective optical coating layer is provided on each of the planar surface and the block surface so that a single laser beam is emitted at two different angles .
