Define semi diameter for surface

[ppfromero]

Hello!

I'm beginner using ray-optics.
I'm unable to define semi diameters for surfaces

I try

sm.add_surface([Radius, Thick, 'Mat, 'CAT', SD])
but SD parameter is not take in account

Here below my system (doublet):

from rayoptics.environment import *

opm = OpticalModel()

sm = opm['seq_model']
osp = opm['optical_spec']
pm = opm['parax_model']
em = opm['ele_model']
pt = opm['part_tree']


osp['fov'] = FieldSpec(osp, key=['object', 'angle'], value=5, flds=[0., 0.7], is_relative=True)
osp['pupil'] = PupilSpec(osp, key=['object', 'pupil'], value=12.5)
osp['wvls'] = WvlSpec([('F', 0.5), (660, 1.0), ('C', 0.5)], ref_wl=1)

opm.system_spec.title = 'My design'
opm.system_spec.dimensions = 'MM'
opm.radius_mode = True
sm.gaps[0].thi=1e10


sm.add_surface([0., 10.])
sm.set_stop()
sm.add_surface([49.57, 7.0, 'H-ZF10', 'CDGM'])
sm.add_surface([-14.41, 1.97, 'H-LAK53B', 'CDGM'])
sm.add_surface([-44.94, 37.49])


opm.update_model()

sm.list_model()
pm.first_order_data()

layout_plt = plt.figure(FigureClass=InteractiveLayout, opt_model=opm).plot()
spot_plt = plt.figure(FigureClass=SpotDiagramFigure, opt_model=opm,scale_type=Fit.All_Same, dpi=200).plot()

opm.save_model("My_design")

I need to define something in order to take in account SD?

Thanks for your help

Here's what I did to make it work, assuming sd=7 for the doublet..

sm.add_surface([0., 10., '', '', 6.25])
sm.set_stop()
sm.add_surface([49.57, 7.0, 'H-ZF10', 'CDGM', 7])
sm.add_surface([-14.41, 1.97, 'H-LAK53B', 'CDGM', 7])
sm.add_surface([-44.94, 37.49, '', '', 7])

sm.do_apertures = False

opm.update_model()

Note there is a flag, do_apertures, in the sequential model that automatically sets the surface clear apertures to pass the vignetted field rays. This will overwrite any apertures that have been entered (or 1.0, which is the default). Turning this off will take whatever apertures that have been entered (with 1.0 as a default). I don't like how hidden this is, but haven't been able to come up with a better approach yet.

Note that if there are no materials entered for the add_surface() call, you have to add empty strings to pad out the argument list to include the sd.

Hope this helps.

Super Mike I miss sm.do_apertures = False
Now it's working!!
