| 摘要 |
The invention provides a non-invasive skin treatment device (200) comprising: a light source (10) constructed for emitting treatment light, an optical system (20) constructed for focusing the treatment light to a focus position (340) inside the skin tissue, and a positioning member (50) having a skin contact surface (52), the positioning member (50) and the optical system (20) being displaceable relative to each other for adapting a distance between the skin contact surface (52) and a final lens element (30) of the optical system. The final lens element, in use, faces a skin surface (300), and the positioning member (50) and the optical system are displaceable relative to each other into a treatment position (Pt) of the optical system (20) and into a further position (Pf1) of the optical system (20) different from the treatment position. In use and in the treatment position, the final lens element of the optical system is in contact with the skin surface without an air gap being present between the final lens element and the skin surface. |

1. A skin treatment device for light-based treatment of skin tissue, the skin treatment device comprising:
a light source constructed for emitting treatment light, an optical system constructed for focusing the treatment light to a focus position inside the skin tissue, and a positioning member having a skin contact surface the positioning member and the optical system being displaceable relative to each other for adapting a distance (d0, d1, d2) between the skin contact surface and a final lens element of the optical system, the final lens element in use facing a skin surface, wherein the positioning member and the optical system are displaceable relative to each other into a treatment position (Pt) of the optical system and into a further position (Pf1, Pf2) of the optical system different from the treatment position (Pt), wherein the skin treatment device is configured to emit, during use, treatment light in the treatment position (Pt) of the optical system and in the further position (Pf1, Pf2) of the optical system, and wherein, in use and in the treatment position (Pt), the final lens element of the optical system is in contact with the skin surface without an air gap being present between the final lens element and the skin surface. |
