AI Technical Summary
Existing zoom lenses suffer from unstable image quality due to changes in the refractive index and coefficient of linear expansion of the plastic lens when the temperature changes, making it difficult to achieve low cost and lightweight design.
By employing a lens combination made of a first polymer compound material and a second polymer compound material with opposite refractive force directions, the focusing performance of the lens group is stabilized by offsetting changes in refractive index and coefficient of linear expansion, and glass lenses are partially replaced to reduce costs.
Stable image quality of zoom lenses at different temperatures has been achieved, reducing costs and achieving weight reduction, thus improving imaging performance.
