Hi every body, 

In order to know the light transmission of an optical system (very simple), I created a source, the sytem, and a receptor. I want to compare irradiance recieved by the receptor while the light is going through the system, and directly to the receptor without the system. But I don't know how to get those information.

 

Here i my simple system:

Here the result in one map:

 

How can I extract irradiance for the whole spectrum to get the transmission curve of my system?

 

Thanks!

Hi Maxime, you can use the spectral seperation to get the irradiance values per nm with this value you can extract the actual spectral dependencies.

 

you can also use python to actually extract these spectral dependencies quickly:

from win32com.client import Dispatch
file =r"D:\Work\OMS4\testabsorbing\test.xmp"
x_pos = 0.0
y_pos = 0.0
width = 10.0
height = 10.0
VPL=Dispatch("XMPViewer.Application")
VPL.OpenFile(file)
w_nb=VPL.SpectralGetNbWavelength
w_min=VPL.WMin
w_max=VPL.WMax
wavelength=[]
energy=[]
signal=[wavelength, energy]
for i, WL in enumerate(range(int(w_min), int(w_max), int((w_max - w_min) / (w_nb - 1)))):
    signal[0].append(WL)
    VPL.SpectralSetActiveWavelength(i)
    signal[1].append(float(VPL.SurfaceRectangleCalculation(x_pos, y_pos, width, height)[6]))

Hi Stephan, 

Sorry for my late answer. I want to extract the whole information in one time, so the 1st method is not idal.

It seems the 2nd method could be nice, but I am far to be a pytyon expert, and when I run your scipt on my computer, it crashes a the first line: "no module nmae win32com.client".

 

Thank you
