pysrw.lib.srwlib.SRWLOptL

class pysrw.lib.srwlib.SRWLOptL(_Fx=1e+23, _Fy=1e+23, _x=0, _y=0)

Bases: SRWLOpt

Optical Element: Thin Lens

__init__(_Fx=1e+23, _Fy=1e+23, _x=0, _y=0)

Parameters:

• _Fx – focal length in horizontal plane [m]

• _Fy – focal length in vertical plane [m]

• _x – horizontal coordinate of center [m]

• _y – vertical coordinate of center [m]

Methods

__init__([_Fx, _Fy, _x, _y])	param _Fx: focal length in horizontal plane [m]
get_orient([_e])
randomize()	Randomizes parameters of optical element according to self.RandParam to simulate e.g. impact of vibrations on coherence (in P-C calculations).
set_rand_par(_rand_par)	Sets list of params to be eventually randomized in some types of calculations :param _rand_par: list of params to be randomized; each element of this list should be: ['param_name', val_avg, val_range, meth]
