Spherical lens is widely used, which can be roughly divided into two categories: 1) making use of the reflective light energy of the spherical lens to reflect back to the incident light source direction, making traffic signs, mixing paint for road marking, or making reflection or photography screen. ② It can be used as grinding medium for metal workpieces, shot peening and cleaning treatment, and filling material for plastic products. Hollow glass beads have the advantages of light weight, high strength and low thermal conductivity. They can be used as lightweight thermal insulation materials for aerospace technology, ship materials and chemical equipment.

We can customized lenses of various styles and sizes according to your request/sample/drawing
