Hello,

I put a multi lens array after a collimated laser beam (fundamental mode). Then I used a fourier lens after the Multi lens array to have an image in reticle plane. But There are a bunch of fourier effect in the reticle plane. How should I get ride of these tiny Fourier effects? Any idea/technique?

Thanks

Farhad
