Greetings to everyone.
I’ve stumble upon this wide-view collimator design and it could be useful for me if RMS spot size radius is less then Airy radius.
The goals:
- RMS spot less then Airy radius,
- EFFL to be very close to 2000mmm and
- that a group of lenses be around 400 mm.
The article and Zemax file are attached.
Thanks for help.
Regards, Ned
