A spherical lens is an optical element with a constant radius surface. Typical uses are to focus, reduce or expand light waves. Lens products are widely used in optical imaging, laser detection, optical communications, life sciences, optical lighting and other related fields.

BoXin produces various kinds of enses using in applications of the cameras, projectors, telescopes, measuring instruments, opticaequipment, and all kinds of the imaging systems. Our professional optics designers and manufacturing engineers are capable of developing a satistied solution for your emand, that either assist you to develop a new product or process the lenses according to your drawing.

Beides producing various spherical enses and cemented lens with optical glass, BoXin also produces a various spherical lenses with crystamaterial. Annual output is 700,000 pieces. The lens with a caliber between 3mm to 1100mm, we process by prototyping or massive sphericalens is treated by project manufacture. Boxin is honored to assist you with success of your project.
