Where to buy an off-axis collimating lens

[rasgar]

I'm tired of looking for mirrors to do my applications, so I was wondering if anyone knows where to find an off-axis collimating lens. I haven't been able to find one myself, not even in edmund optics or other major suppliers. If anyone does know, can you tell me where to get it and the place that has the best price. If it must be custom-made, please tell me the cheapest company to do that.

Fecker and Unertl used to do off-axis systems --- nowadays?

That didn't help. I think you might have spelled something incorrectly because I searched for Fecker and Unertl, yet found only binoculars, but no lens-related articles.
