Optical element with stress distributing supporting structure

An optical element defining an optical axis and comprising:

• a supporting structure,
• a bendable cover member attached to the supporting structure, wherein an interface between the bendable cover member and the supporting structure defines an interface plane,
• one or more actuators arranged for shaping said bendable cover member into a desired shape,
• at least one deformable transparent lens body attached to the bendable cover member,
• wherein
• one or more of:
• a dimension in a direction being parallel with the optical axis, and/or
• a Young's modulus
• of the supporting structure on one side of the interface plane increases gradually and/or in a plurality of steps along at least a portion of a line being orthogonal to the optical axis and intersecting the optical axis and in a direction away from the optical axis, wherein said line spans a range from a point at an inner edge of the interface and a point more distantly placed with respect to the optical axis,
• and/or wherein
• a dimension of the bendable cover member in a direction being parallel with the optical axis is larger
• at at least one first point at an inner edge of the interface, than
• at at least one second point on a line from said first point to the optical axis,
• and wherein the Young's modulus of the supporting structure is less than the Young's modulus of the bendable cover member.
