OPTICAL DEVICE AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240159987 titled 'OPTICAL DEVICE AND IMAGE PICKUP APPARATUS

Simplified Explanation

The patent application describes an optical device with multiple lens units, drive units to move the lens units along the optical axis, a stop member with a variable aperture diameter, and a drive unit to change the aperture diameter. The arrangement of the drive units and stop member allows for precise control and adjustment of the optical system.

  • The optical device includes first to fourth lens units and corresponding drive units to move them along the optical axis.
  • A stop member with a variable aperture diameter is present, along with a drive unit to adjust the aperture size.
  • The drive unit closest to the image among the lens units has the longest length along the optical axis.
  • The drive units and the aperture adjustment unit are arranged in different spaces around the optical axis.
