[Laser] Fresnel lenses

[Paul Cianciolo]

Folks,

I wonder if anyone has used a 10" or so diameter for a receive antenna?

The problem I see is the relatively short focal lengths.  This combined with
the a 2.5 mm dia. detector
makes for a pretty wide FOV.

The fresnel's have tried have not been the most well focused lens's.


Just curios.


 3DLEN.COM perhaps?

What are you guys using as a FOV for NLOS receivers?
