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
