Latest Patents

Cai’s listed patents describe two optical lens designs. One design uses front and rear lens groups, each with positive diopters, separated by an aperture. The front group contains at least two aspherical lenses, while the rear group includes at least one adhered lens and an aspheric lens. The design specifies a ratio between the effective focal lengths of the front and rear groups that is greater than 0.35 and less than 0.6.

The other design features a front group with non-rotationally symmetrical second and third lens elements, a cemented lens in the rear group, and an aperture between the groups. It is designed for a half field of view greater than 90 degrees in both horizontal and vertical directions and specifies relationships among its effective focal lengths and lens parameters.
