30mm Laser Focus lens

Laser focus lens, also known as laser focusing mirrors or lenses, are optical components that adjust the angle and focal point of a laser beam. They enhance the beam's penetration and energy density by converging a divergent laser beam into a small spot. Based on light refraction and focusing effects, these lenses change the beam's direction of propagation due to the lens material's refractive index and shape. Specifically, the curvature and shape of the lens refract the incident beam, causing it to converge at the focal point. This results in high light intensity and power density.

Laser focus lens have diverse applications in laser processing, including laser cutting, marking, welding, engraving, drilling, ranging, and more. In laser cutting, they converge the beam to a small point, enabling intricate patterns and shapes to be cut. In laser marking, they adjust the beam's angle and focal point for precise inscription. In laser welding, they improve welding efficiency and quality by focusing the beam. By focusing divergent laser beams into small spots, these lenses fulfill the requirements of various laser processing applications.
