I am trying to take a known set of Fringe Zernike Coefficients, and insert them into a zemax optical system model as a Zernike Fringe Phase surface. I’ve gotten as far as being able to insert the surface and set it as a Zernike Fringe Phase type, but I haven’t had any success with entering coefficient values into the LDE. 

I’ve tried 

LDE.GetSurfaceAt(28).GetCellAt(14).DoubleValue = value

where value is a float, but it throws an exception saying that a Double was expected and it got a string. I’ve also tried to just return a value that I’ve typed in manually, but had no success that way either. Can anyone point me in the right direction here? It seems like it should be simple with entering numbers into the LDE, but nothing has seemed to work so far. 

Thanks
