  • Publication number: 20230314762
    Abstract: An optical imaging lens, in order from an object side to an image side along an optical axis, includes a first lens assembly, an aperture, and a second lens assembly. The first lens assembly includes a first lens having negative refractive power and a second lens having positive refractive power. The second lens assembly includes a third lens having positive refractive power, a fourth lens having negative refractive power, and a fifth lens having positive refractive power. The optical imaging lens satisfies: ?5<fg1/F<?3.5 and 1.5<fg2/F<2.5; F is a focal length of the optical imaging lens; fg1 is a focal length of the first lens assembly; fg2 is a focal length of the second lens assembly, thereby achieving the effect of high image quality.

  • Publication number: 20230134267
    Abstract: An optical imaging lens, in order from an object side to an image side along an optical axis, includes a first lens assembly with negative refractive power, an aperture, and a second lens assembly with positive refractive power. The first lens assembly includes a first lens having negative refractive power, a second lens having negative refractive power, and a third lens having positive refractive power. The second lens assembly includes a fourth lens having positive refractive power, a fifth lens having negative refractive power, and a sixth lens having positive refractive power. The optical imaging lens satisfies ?0.6?F/fg1??0.3 and 0.25?F/fg2?0.57, wherein F is a focal length of the optical imaging lens, fg1 is a focal length of the first lens assembly, and fg2 is a focal length of the second lens assembly, thereby achieving the effect of high image quality and low distortion.

  • Publication number: 20230001036
    Abstract: A scented candle device includes an electromagnetic base having a casing that defines a base space and that has a top surface, and an electromagnetic unit disposed in the base space for generating a magnetic field. An electromagnetically heated scented candle is disposed on the top surface of the casing, and includes a container defining a receiving space, and a scented candle body received in the receiving space. A magnetically conductive heating member is disposed between the top surface of the casing and the container, and generates heat energy after interacting with the magnetic field of the electromagnetic unit for heating the scented candle body.
