Description
A simple X-ray compound refractive lens (CRL) with a profile of the parabola in rotation simulates the photons' movement on passing through it. The CRL focuses in 2D Example: Lens_parab(material_datafile = "Be.txt", r=200e-6, r_ap=0.5e-3, d=50e-6, N=16)
Input parameters
Parameters in boldface are required; the others are optional.| Name | Unit | Description | Default | |

| r | m | Radius of curvature (circular approximation at the tip of the profile). | 0.5e-3 | |
| r_ap | m | Radius of circular aperture, which also defines the depth of the lens profile. | 1.4e-3 | |
| d | m | Distance between two surfaces of the lens along the propagation axis. | .1e-3 | |
| N | m | Number of single lenses in a stack. | 1 | |
| rough_z | rad | RMS value of random slope error along z. | 0 | |
| rough_xy | rad | RMS value of random slope error along x and y. | 0 |
| AT ( | , | , | ) RELATIVE | |||
|---|---|---|---|---|---|---|
| ROTATED ( | , | , | ) RELATIVE |
