I'm of the put up or shut up mentality.
Ive got cc xtals next week, im buying profs today. Let me buy one of yours.
I would think if assmodeus xtal is far superior than he would not have an issue selling one to you. Right? If CC is so far beneath it, why don’t we let the pictures speak for themselves.....

My 2 cents I know it isn't worth much, if my product was superior to my competitors and I had an audience I knew my product could sway them into favoriting mine over the other competitors I would be donating a few not one but a few to secure my future...
just me though I can't speak for anyone else of course.

That would be a good idea, but we're even offering to purchase and we can't get them. Besides by purchasing then we're truly objective and no one could claim that we're writing a positive review for free samples.
That's a great shot. I'm not sure which crystal it is, but I love the look. The other hulk in this thread had a green hue on the cyclops. (Maybe it was the angle the picture was taken from)
I feel you, my point is reading post #52 just broke my heart.
It could of gone a little more like this... Hey guys thanks for the plug shoot me an address and I'll shoot out a couple for comparison if you like it cool if not let me know what you don't like about it and I'll work on it.
Thanks Again looking forward to doing business in the future.

Sorry but prof's blackhole is not gen spec. There is too much of a 'black effect' in the cyclops which gen does not have as pronounced. Concerning the CC crystals it actually (in pictures) looks 99% gen like.
Post 52 was a great and honest post. I wished the thread had stayed that positive and you're right it would have been the perfect opportunity to offer to provide samples (whether at cost or free) I really wanted this to be a fair, accurate, honest, and positive thread. Constructive criticism is still wanted and warranted.
BTW, CC has listened to feedback from those who have received their green tint crystal and have now offered a blue tint version for our very Niche market.
Another person has offered to send one of their crystals to 2fake4u for him to do an honest comparison. Both of these were smart business decisions, IMO.

I'd personally love to see a true, blinded head to head comparison. Well, I guess it'll be prof vs CC vs gen with one no show? If I cannot see a product compared to gen (the control in this little experiment) as well as the alternatives (read: options as they are not direct competitors), I would not consider it for my next franken project. This is my 2 cents. As of now, they each fill a niche and price point so it would be good business... Just like every other flaw in a rep, each individual will have their own wants and desires. Some may only consider one with an LEC, some want the closest to gen, some want the least expensive route. This would answer these and other questions.
When did AR work went from fun upgrading to fighting? When I was offering AR, we did not have any fights. I don't like this development.

You are the OG of Gray Market AR Sunnydale!!! Salute!
And you are right. This thread is crazy!! Lol
You mean that prof's AR formula make it easier to be scratched? And the ones with the green hue are resistant?
For the clarity I have to agree that profs is the best I have ever seen!

just an FYI, but here is the basic physics involved
The transmission properties of a coating are dependent upon the wavelength of light being used, the substrate's index of refraction, the index of refraction of the coating, the thickness of the coating, and the angle of the incident light. The refraction of the coating is where the magic occurs and where the scientist determines, mostly by trial and error around a small hemisphere, what yields his or her ideal outcome. A portion of this is and always will be art- science has come a long way in optics but in a lab there are unaccounted variances that happen on a consistent basis
In an ideal situation, relative phase shift between the beam reflected at the upper and lower boundary of the thin film should be 180°. Destructive interference between the two reflected beams occurs, thereby cancelling both beams before they exit the surface. The optical thickness of the coating must be an odd number of quarter wavelengths (?/4, where ? is the design wavelength or wavelength being optimized for peak performance), in order to achieve the desired path difference of one half wavelength between the reflected beams, which leads to their cancellation. Now you got that?
The equation for determining the index of refraction of the thin film needed for complete cancellation of the two beams is: sorry but the superscript and subscripts don't work in this interface and even typing it in word and importing it loses the sub and superscripts. teh 1/2 is a superscript and teh f,0 and s are subscripts
Nf=(N0,Ns) 1/2
Nf is the index of refraction of the thin film
N0 is the index of refraction of air (or the incident material)
Ns is the index of refraction of the substrate

BTW- from the national association of optical engineers:
"Each manufacturer has their own proprietary formula for the mineral combinations that make up the multi-layered AR coatings"
so as mentioned in this tread, there are no "secret": formulas- not true. I don't remember if it was Omega or Breitling, but one of those brought suit for theft of a proprietary AR formula
