aspherics in parallel

[3D black mag]

Hello I am building an aspheric maglite and am wondering what would happen if I put two aspheric lens in series.

And I was also wondering, I bought a 52mm by 18mm aspheric lens from DX but then I saw Kai's 52mm by 25mm aspheric would there be a noticable difference in the two?

You will have a single bright beam. The aspheric beams are offset from each other a few inches but are still coplanar, so there won't be any angular divergence.

A thicker lens will have a shorter focal length and that results in better light collection.

Do you mean in series (two aspherics stacked) or parallel (side by side)?

Thank you morelite for correcting me I did mean series. I will edit my post.

How about taking a few pics during assembly?
