Micro Sphere Lenses

Name: Micro Sphere Lenses
Brand: Shenzhen Solar Valley Scitech Development Co., Ltd.

Micro lens is manufactured by two processes, one is that the microlens is molded by high temperature, which has the advantages of low production cost and high precision, and is suitable for the mass production of aspherical microlenses. The second is the use of high-precision CNC machine tool fine grinding, grinding, measuring, polishing process processing and forming, suitable for optical glass, optical quartz, sapphire, infrared crystal spherical and aspherical microlens manufacturing. Microlens is the core component of a variety of optical systems, widely used in medical instruments, optical fiber transmission equipment, microimaging systems, etc. Solar Valley high-precision microlens can greatly improve the imaging effect.
