Laser Optical Lens

A laser optical lens is an optical element used to manipulate a laser beam. It can focus, disperse, and deflect laser beams to meet different application requirements. Laser optical lenses are usually made of optical glass or crystals, with specific curvature and surface shape. According to its shape and function, laser optical lenses can be divided into convex and concave lenses. A convex lens can focus a laser beam onto a single point, making the beam more concentrated and powerful. This type of lens is commonly used in applications such as laser cutting, laser marking, and laser welding. A concave lens has the function of dispersing the laser beam, which can diffuse the laser beam into a larger angle. This type of lens is commonly used in applications such as laser display, laser projection, and LiDAR. In addition to convex and concave lenses, there are also some special shaped laser optical lenses, such as prisms, prism combinations, and aspherical lenses. They can be used to adjust the polarization, wavefront shape, and optical path difference of laser beams.
