Thanks Drakkith, but it doesn't matter my setup. The question is simple, I want to know if there's a way to get the same FL but with a shorter distance than with a single lens. For example, in a telescope, you can add a Barlow lens in the middle of two, to extend magnification, so in fact...

But..does this FL10mm lens provide same beam specs than FL50mm lens? I'm afraid not...Again, idea is, same beam properties than with a FL50mm, but with shorter distance than 50mm (or near)...any ideas? thanks guys anyway

A shorter focal lens will not provide the same beam properties than FL50, I'm thinking more towards a Barlow lens with a 3 lens system...

Thanks for your reply. Yes, a suggestion and Yes, I know it will diverge. But this don't ask my question. Question is: Could I place some lenses (or something?) to get a much smaller setup distance than 50mm, and get the same light behaviour than with a FL50mm lens? thanks! In other words...

Hello Everybody, I'm David from Spain, and happy to be here. We have a LED that needs a FL50mm collimator which is focused to infinite, because we want parallel rays. So the lens is at a distance 50mm (approx) from the led. However, 50mm is too much distance for our design, so the question is...
