Radiation focussing element |
| abstract |
The or at least one surface of a reflective or transmissive radiation focussing element is provided with at least one phase or amplitude diffraction grating that is distorted substantially according to a quadratic function. The surface or the opposed surface may also be provided with an aperture. The element is useful in three dimensional imaging and wavefront sensing systems. |
