Adaptive Lens System
First Claim
Patent Images
1. An adaptive lens system for laser materials processing, the adaptive lens system comprising:
- a first deformable lens and a second deformable lens spaced apart from each other in the direction of a common optical axis;
a chamber defined between a first surface of the first deformable lens and a first surface of the second deformable lens; and
a device operable to change the distance, along the optical axis, between the first surface of the first deformable lens and the first surface of the second deformable lens, thereby changing a pressure in the chamber and deforming the first deformable lens and the second deformable lens.

Abstract
An adaptive lens system for laser materials processing, for example, in the high-power range of at least approximately 1 kW, includes two deformable lens surfaces spaced apart from each other in the direction of the optical axis, a chamber formed between the two lens surfaces and filled with a fluid, and a device for changing the distance between the two lens surfaces along the optical axis.
