Powell Lens Equations for Gaussian to Flat Top Beam Conversion

[sgn]

I am a Post graduation student and I am doing a project on the conversion of a Gaussian beam into a flat top beam using optical components. I have found that the best component to do the same is a Powell lens. I would like to know more about the equations connecting the input beam diameter, output beam diameter, wavelength of the light and the fan angle of a Powell lens.

I don't know much about Powel Lenses, but i found this thesis discussing this kind of lenses, there are a few equations and simulations aswell.

Also, you can download the EDU version of OSLO optical modeling software and make a Powell lens in it and experiment how they work.

Thank you for your Reply.
I have already read the article but couldn't"find the relation from this one.
Still I am happy to tell you that I have got the relation from a Patented document.

Now that I have found the relation and working of the Powell lens, I would like to simulate it using ZEMAX optic studio software.
Can anyone please help me with the steps to be carried out in ZEMAX to generate a Powell lens and its properties.

You should post a thread at the Zemax General Discussion Forum: http://forum.zemax.com/Forum27.aspx

I don't know any simple method to simulate a powell lens in Zemax. You could try the Part Designer in Zemax to draw a Powell lens, or use a solid modelling CAD software (AutoCAD, Inventor, SolidEdge, SolidWorks etc.) to draw it, and then import it to Zemax.
