Cylindrical Lenses Series We Made

plano convex cylindrical lens

plane convex cylindrical lenses

Plano-convex cylindrical lenses have a unique structure with one flat surface and one convex surface, capable of focusing incident parallel light into a fine line. These lenses play an important role in technical applications such as laser beam shaping and fiber coupling. By precisely controlling the light focusing, plano-convex cylindrical lenses can effectively improve the optical performance and efficiency of systems.

plano concave cylindrical lens

plano concave cylindrical lenses

Plano-concave cylindrical lenses have one flat side and one concave side. Their main function is to spread the light beam into a line shape, thus playing an important role in areas such as spectrometers and barcode scanners. By adjusting the propagation direction and shape of the light beam, plano-concave cylindrical lenses can optimize the application effects of optical systems.

meniscus cylindrical lens

meniscus cylindrical lenses

Meniscus cylindrical lenses feature one convex and one concave cylindrical surface. This unique design combines the properties of both positive and negative cylindrical lenses. Applications of meniscus cylindrical lenses include laser diode circularization, astigmatism compensation in imaging systems, beam shaping, and optical system miniaturization. Their ability to reshape beams while providing aberration correction makes them versatile for laser material processing, biomedical optics, and other photonic applications.

double convex cylindrical lens

Bi-convex cylindrical lenses feature a design with both sides convex, giving them stronger focusing power. They are particularly suitable for applications requiring high energy density, such as laser marking and material processing. By improving the focusing efficiency of the light beam, bi-convex cylindrical lenses can bring higher precision and effects to these applications.

double concave

Both surfaces of bi-concave cylindrical lenses are concave, allowing them to provide a larger beam expansion angle, suitable for applications requiring a wide field of view, such as holographic illumination and 3D scanning. By adjusting the beam expansion range, bi-concave cylindrical lenses can meet specific optical needs.

aspherial cylindrical lens

aspherical cylindrical lenses

By adopting an aspheric design, aspheric cylindrical lenses effectively reduce aberrations, providing higher imaging quality. These lenses are suitable for applications with strict imaging performance requirements, such as optical inspection and medical imaging. The high-precision design of aspheric cylindrical lenses ensures optimal imaging effects for optical systems.
