  • Publication number: 20200371321
    Abstract: A wide-angle lens includes a front group, an aperture, a rear group, and an infrared cut filter. The front group includes a first lens and a second lens arranged in order from a side closest to an object to an image side. In the wide-angle lens, an anti-reflection layer having a reflectance of 1.5% or less in a wavelength range from nm to 850 nm is provided on a lens surface of the first lens on the image side to suppress an occurrence of a ghost caused by light passing through a peripheral portion of the lens surface. Therefore, even if a film forming the anti-reflection layer is thinner than an appropriate value at the peripheral portion of the lens surface, the anti-reflection layer appropriately prevents reflection of light in a long wavelength range.

  • Patent number: 10795236
    Abstract: In an optical unit with shake correction function, a first stopper mechanism configured to define a swinging range of a movable member is composed of: a first projection part for stopper and a second projection part for stopper, both of which are provided in a camera module; and a projection portion (abutment target) of a holder bottom plate member. Therefore, when the first projection part for stopper and the second projection part for stopper; and the projection portion of the holder bottom plate member abut against each other and then movement in the Z axis direction of the movable member is restricted, the camera module does not move in the Z axis direction any more. Accordingly, the camera module does not slip off from a camera module holder of the movable member.
