Avantier Inc. High-Quality Plano-Convex Lenses

Avantier specializes in the manufacturing of high-quality plano-convex lenses, which are optical lenses with a positive focal length. These lenses are versatile and can be tailored to suit your specific application by offering a wide range of sizes, substrates, and coatings. Plano-convex lenses are particularly suitable for infinite conjugate systems and simple imaging tasks. They are well-suited for applications involving monochromatic illumination and light collimation. Due to their design, with one flat surface and one convex surface, the orientation of the lens is crucial. In most cases, the flat surface should be oriented towards the focal plane. Our lenses are highly versatile and find applications across various industries, including industrial, robotics, pharmaceutical, and defense sectors. When utilized in laser cutting, plano-convex lenses are most effective for high-power cutting applications and when dealing with thick materials. In such scenarios, the plano-convex lens provides a wider cut width, enabling the laser’s oxygen assist to enter the cut and enhance the cutting process. Additionally, these lenses offer a greater depth of field, resulting in a taperless edge.
