  • Adaptive optics system and optical device
    Patent number: 10254538
    Abstract: The present invention is intended to provide an adaptive optics system and an optical device that allow correction of wavefront phase aberration with higher accuracy than before and have a wider correction range than the conventional ones, regardless of the distance between the observation target and the fluctuation layer, and the size of the observation target. An adaptive optics system includes: a wavefront phase modulator that makes aberration correction to incident light and emits the corrected light; and an imaging-conjugated position adjustment mechanism that adjusts freely within a specimen the position of a surface imaging-conjugated with a fluctuation correction surface formed by the wavefront phase modulator. The imaging-conjugated position adjustment mechanism adjusts the fluctuation correction surface to be imaging-conjugated with a fluctuation layer existing in the specimen.

  • Lens assembly and imaging device
    Patent number: 10254502
    Abstract: A lens assembly and an imaging device for realizing low-profileness, and for effectively compensating a change in back focus generated by a change in atmospheric temperature. A lens holder contained in a lens assembly of an imaging device includes an inner frame on which a lens unit is attached, a holding frame provided with a lower end surface fixing a positional relationship with an image sensor, a linking frame for linking the inner frame and the holding frame. The lens holder extends and contracts so that the inner frame and the holding frame distance the lens unit from the image sensor when back focus of the lens unit extends due to change in atmospheric temperature, and brings the lens unit closer to the image sensor when the back focus contracts.
