Oscilloscope lenses are not "optimized" for any range of reproduction ratios.
They're designed for one specific ratio (1:1), and that's all. If they work at any other, that's OK.
They have no chromatic correction because they worked with monochromatic light (green, occasionally blue).
Also, they're generally uncoated.

If you believe you can, or you believe you can't... you're right.
I've had 5 or 6, made by Wollensak, Dallmeyer, Mamiya and a couple of others, all coated.
Was thinking along the lines of some teflon dry lube, I'll have a go at using it in a bit (the saga of being told one shade of paint can't be used in a conservation area, yet another shade that looks almost exactly the same can. . . the joy of renovations :P )Originally Posted by Ian Greenhalgh
I think the Alphax is designed to run dry, so check if it should be lubed before you do, it might need cleaning instead. You could certainly use the lens, you might gt something nice and artistic, post the results when you do, I'm intrigued.
All part of the fun then. Plus another 'excuse' to try x-ray film. . .
