I just found an instruction manual for some software. Can you download the software somewhere?

[Dan Fromm]

ic-racer, search for oslo and free and student version and with luck you'll find it. The full version that does all the manual talks about isn't, alas, free. If you read French you might want to try Eric Beltrando's program 030, which I think is still available on www.dioptrique.info

I've recently finished designing a petzval with OSLO Edu, there is quite a steep learning curve, but its not too bad, not as bad as say, vuescan.

Winlens (LINOS ex Rodenstock) is free http://www.winlens.de/

Are there any of these programs that run on a Mac?
