What a difference good douoble AR coating makes

[alfajor]

How does one contact mrprof about AR coating services?

I need new AR on my Tag Carrerra 1887 which I scratched.

Thanks.

Many gens don't use double AR... such as AP's. I've debated what I like more... being Gen like or having it look better.

Yes, both are single AR coated but AP rep crystals suck, they lack the clarity and transparency of the gen crystal.
Side by side, I believe an AP rep with a quality double AR crystal looks much closer to gen, even if it reflects a bit less light.

Decent exposure pic of how clear a Gen AP crystal is, reps are nowhere near this:
