Latest Patents

**Camera Optical Lens.** This design describes a six-element optical system that includes lenses with alternating positive and negative refractive powers, along with a first optical member featuring curved objective and image surfaces and a reflective surface. The specified relationships include an Abbe number of at least 60 for the first optical member and a ratio of the first member’s image-surface curvature radius to the second lens’s objective-surface curvature radius between 4.50 and 50.00. The design aims to improve an aspherical prismatic lens and enable a large-aperture, periscope-style configuration.

**Camera Optical Lens.** This patent describes six lenses arranged from the object side to the image side, with positive and negative refractive powers alternating through the first five lenses and a negative-power sixth lens. It specifies relationships among focal lengths, curvature radii, and lens spacing. The stated goal is to provide good optical performance while meeting design requirements for a large aperture, wide angle, and ultra-thin construction.
