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...

Thanks for the replies Drakkith and SteamKing, So if this is true, I just wondered why don't they use echelle spectrographs in optical sciences, where you have 2 dimensional spectrum (orders on top of each others). When astronomers need high resolution they use these kind of instruments...

If you take the spectra of a star you usually have a big primary mirror (lets say 1m) to get a lot of light, and use an exposure time usually several tens of minutes. Can one use an astronomical spectrograph for a led/arclamp light source? How does the light intensity of a star compares to...

Sadly the hamamatsu housing for the 75W lamp of Hamamatsu does not contain optics, only the housing of the 150W arc lamp. http://goo.gl/X1HYbz page 13

It is a bare bulb, it has a housing but it does not contain any optics, it is for temperature control. We collimate the light with a lens, and then focus it onto the bundle with another lens. The application would be a transmission measurement system, from the light bundle we take the fibers...

The ellipsoid mirror and the tin foil ball is not an option, our Xe lamp is in a temperature controlled box, with a hole in it, where the Xe arc is. But maybe putting a mirror behind the light source, we could salvage some of the light which is radiating in the direction of the box and not out...

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. http://goo.gl/TdtMLt Also, you can download the EDU version of OSLO optical modeling software and make a Powell lens in it and experiment how they...

Hey, we are trying to couple the light of a 75 W Xe Arc Lamp (Hamamatsu L2194) into a 800um(0,8mm) diameter fiber bundle (7 fibers). Now we have 2 plano convex lenses (25mm diameter, 30mm EFL, edmund serial #45-364), the first for collimating the second for focusing onto the fiber. We are...
