Precision injection molding refers to the process of manufacturing precise plastic parts using injection molding technology. Injection molding refers to the process of melting plastic raw materials, injecting them into the mold through mold pressure, and then cooling and solidifying them to obtain the desired shape of plastic parts.
Precision injection molded non spherical lenses refer to non spherical lenses manufactured using precision injection molding technology. The surface shape of this lens can be elliptical or curved, depending on the requirements of the applied optical system.
Precision injection molded non spherical lenses have the advantages of low cost, short production cycle, and high processing accuracy. Its manufacturing process is relatively simple and suitable for large-scale production. However, due to the poor optical properties of plastic materials, the optical performance of precision injection molded non spherical lenses is usually inferior to lenses made of metal or glass.
Precision injection molded plastic non spherical lens is a type of plastic lens manufactured through precision injection molding technology, and its surface shape is not a simple spherical surface, but a complex non spherical surface. This type of lens is widely used in photography, optics, electronics, and consumer electronics products, especially in situations that require lightweight, cost-effective, and large-scale production. The design of non spherical lenses allows for more precise control of light, thereby improving imaging quality, reducing aberrations, and enhancing overall system performance.
Precision injection molded plastic non spherical lenses are widely used in multiple fields, including:
- Consumer Electronics: Such as mobile phone cameras, digital cameras, virtual reality helmets, and other portable devices.
- car: Such as in car cameras, sensors, and HUD (Head Up Display).
- lighting: Used for beam shaping in LED lighting.
- medical equipment: Such as certain types of endoscopes and optical diagnostic instruments.
