20mm Laser Focus Lens

Laser focus lens, also known as laser focusing mirrors or focusing lenses, are optical elements capable of adjusting the angle and focal point of a laser beam. They can converge a divergent laser beam into a small spot, thereby enhancing the laser beam's penetration and energy density. The working principle of laser focusing lenses is primarily based on light refraction and focusing effects. When a laser beam passes through the lens, the direction of beam propagation changes due to the influence of the lens material's refractive index and shape, achieving a focusing effect. Specifically, the lens refracts the incident beam through its curvature and shape, causing the beam to converge at the focal point. Laser focusing lenses can focus the laser beam onto a very small focal point, resulting in high light intensity and power density. These lenses can adjust the angle of the laser beam to ensure precise illumination of the target position. Laser focusing lenses have a wide range of applications in the field of laser processing, including but not limited to:

Laser cutting: During laser cutting, focusing lenses can converge the laser beam to a very small point, enabling the laser to penetrate the material and cut out intricate patterns and shapes.

Laser marking: Laser focusing lenses can adjust the angle and focal point of the laser beam to ensure precise inscription of the desired marks and imprints.

Laser welding: In laser welding processes, focusing lenses can focus the laser beam, improving welding efficiency and quality.

Furthermore, laser focus lens are widely used in laser engraving, laser drilling, laser ranging, and other fields. By focusing divergent laser beams into small spots, these lenses enhance the laser beam's penetration and energy density, fulfilling the requirements of various laser processing applications.
