# Gaussianoptics

Python library for the simulation of gaussian beams according to ray optics.

You can build an optical bench with the following elements (see test.py for an example):
-    'path', refractive index , position[mm], (relative: 'r', absolute: 'a' (position is the end position), filling: 'f')
-    'thinlens', f [mm] , position[mm], (relative: 'r', absolute: 'a')
-    'thicklens',  	[   n1 = refractive index outside of the lens,
                       n2 = refractive index of the lens itself (inside the lens),
                       R1 = Radius of curvature of First surface,
                       R2 = Radius of curvature of Second surface,
                       t = center thickness of lens] , position[mm], (relative: 'r', absolute: 'a')
-    'flatmirror', 0 , position[mm], (relative: 'r', absolute: 'a')
-    'curvedmirror', [R [mm],
                     angle [°],
                     plane (0=tangential, 1=sagittal)], position[mm], (relative: 'r', absolute: 'a')
-    'flatrefraction', [    n1 = initial refractive index,
                           n2 = final refractive index] , position[mm], (relative: 'r', absolute: 'a')
-    'curvedrefraction', [  n1 = initial refractive index,
                           n2 = final refractive index,
                           R = radius of curvature R > 0 for convex (centre of
                           curvature after interface)], position[mm], (relative: 'r', absolute: 'a')


example: opticalbench = ['path',1,0.050,'a''thinlens',0.05,0.100,'r''path',[1,0,0,0,0],0,'f''thinlens',[0.15,0,0,0,0],0.200,'r']

TODOs:
- check if 'path' is first and last element
- find 'empty space'
- normalize curve by refractive index other than 1
