SOLIS Beijing Co., Ltd.

A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis.

Our lenses are made from materials such as optical glasses or crystals, and are ground and polished or molded to a desired shape. A lens can focus light to form an image, unlike a prsim, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, electron lenses, acoustic lenses, or explosive lenses. 

1.We supply the standard optical lens such as the following 6 types: 

Double Convex:

Is machined from two identical spheres. Since the two spherical faces are equal in radius, coma, distortion and chromatic aberration are effectively eliminated. They combine with other lenses to form an imagining system.  

Plano Convex:

Are used in many applications, including the telescopes, sights, magnifiers, light receivers and condensers. A plano-convex lens consists of a plane and a sphere which combine with other lenses to form an imaging system.

Double Concave:

Is machined from two identical concave spherical surfaces. They form a negative focal length. Double concave lenses are often used in systems for beam expansion or increased focal length, and are also used in laser beam expanders, light readers, viewers and projection systems.

Plano Concave:

Is machined from a flat surface and a concave spherical surface. They form a negative focal length. Plano concave lenses are often used in systems to expand the beam or increase the length of the focal length.

Converging Meniscus, Diverging Meniscus and Crescent Lens:

If the lens is a convex-concave lens, then the convergence or divergence of the lens depends on the relative curvature of the two curved surfaces. If the two are equal (the crescent lens), the passing light beam neither converges nor diverge.

2.The high presion tailor-made optical lenses for instance: Aspherical, Cylindrical, Ball, Rod, Hemispherical, dome and aspherical lens can be supplied too.

Materials can be optional and customer-designed: 

Optical Glasses, Fused Silica Glass, Sapphire, CaF2, Ge, Si, ZnSe, PMMA, MgF2, BK7 Glass and etc.
