Latest Patents

Yuan-Long Cai holds a patent for a wide angle lens that includes, in order from the object side to the image side along an optical axis, a negative first lens, a negative second lens, a positive third lens, a positive fourth lens, a negative fifth lens, and a positive sixth lens. The sixth lens is adhered to the fifth lens to form a doublet lens. This design satisfies the condition of SD2/R2 > 0.6, where SD2 is half of an effective aperture of a surface of the first lens facing the image side, and R2 is a radius of curvature of that surface. The resulting wide angle lens can achieve a field of view greater than 140 degrees and is compatible with large-sized photosensitive components, such as 1/2.3” sensors.
