Abstract

본 발명은 레이져빔의 집속렌즈에 부분반사층을 코팅해서 레이져 레이다의 관측각을 향상시킬 수 있도록 한 반사코팅층을 가지는 레이져빔의 집속렌즈에 관한 것이다. 본 발명은 일면은 평면으로 되고 일면은 볼록면으로 되어 레이져빔을 집속하는 집속렌즈에 있어서, 상기 평면 및 블록면에 각각 부분반사 광학코팅층을 시설하여 단일의 레이져비이 2개의 서로 다른 각으로 발사하도록 한 것을 특징으로 한다.The present invention relates to a laser beam focusing lens having a reflective coating layer which can be coated on the laser beam focusing lens to improve the viewing angle of the laser radar. The present invention provides a focusing lens for focusing a laser beam on one surface and a convex surface, each of which has a partially reflective optical coating layer on the plane and the block surface, so that a single laser beam can be fired at two different angles. It is characterized by one.
