If you pull this off commercially, you will be the stuff of legend!

You may want to consider applying for US and/or other country patents on the design prior to publicly disclosing prototypes.

Inventors should be rewarded for their innovations, IMO.

Regards,

Jim

Thank you, Jim. It already in "Patent pending" status.

Valery.

I'd love to know if this same design is being considered in smaller aperture sizes in the near future as well?

Down to 150mm or 160mm or 165mm - yes. And up to 320mm.

I don't care if new technology is simpler and or cheaper to make, it will probably cost more or the same!

They SURE will cost significantly less. And as bigger size, as the difference will be more significant.

Bravo! However, I am also skeptical... it seems like for this design to achieve optimal performance each fresnel lens will have to be perfectly matched to each doublet, no?

So what ever happened with optical surfaces needing to be better than quarter wave? The P/V and RMS on a fresnel lens has to be horrendous. It's not like CA is the only design spec that matters.

Hey Valery no one thought the world was round either.
I have full confidence in your new design. When our Passions guides and drives us wonderful things happen.

ValeryD, I think You should be more polite with potential customers. For some people tongue helps, but for somebody it is the biggest enemy.

well Valery is famous for his acerbic wit :-D

personally I'd love to see a product that beats what the multi-billion-dollar, 2nd-largest-patent-producer-in-the-world Canon can do. Better for us customers, and I don't mind Valery's responses, IF it is indeed true.

Heck Valery might get rich selling the technology to Canon..

but, until I see it, I will have to reserve judgment.

I think it is better to sell the tech to Nikon.

But not sure it is demanded well by them at such large sizes.
At smaller sizes (3" and smaller) the leader is Schott.
Their DOEs are much more advanced and have Strehl up to 0.95.

BTW The very first our attempt (November 2010) was partially succeeded - no colors, but a lot of scattered light. The simple mistake has been corrected and now a scattered light is within the limits of norm defined by theory.

Valery.

interesting! I thought Canon had a near-monopoly on this. So why isn't Nikon sourcing from say Schott?

http://www.schott.com/advanced_optics/english/our_products/process_components/lenses/doe.html

Valery,

Wouldn't it be also possible to use a sub-diameter DOE? or does the design require that the DOE is very close (or molded even) to the rear element?

"Diffractive lenses can be used to reduce the number of elements in conventional lens systems and eliminate the need for exotic materials in correcting chromatic aberrations."

By Valery's description, it seems ARIES has gotten the scatter down to below the spot size.

Again, we'd all love to see something like that. I do note though that this will not make small ED lenses (say under 5") any cheaper, that technology seems to have been mastered by the Chinese..

so this technology will mostly be used for larger lenses (say 6" and up). Since iStar already is selling large achromats, we can guess how much these will cost -- since an iStar 150 f/8 is $1200 and a Tak TOA 150/7.3 is $11K I would expect this technology would have to be below $3K for a 6" I would guess.. if it was below $2K for a 6" then that would be the bomb!

This could be a game changer for sure. Good luck Valery, the visual masses await your final release...

Valery,

First, congratulations to you for successfully tackling the scatter problem of your new DOEs refractors.

What advantages do you think one of your, let's say 10 inch, refractor using DOEs will offer compared to a 10 inch Fraunhofer achromat combined with a sub-aperture corrector (a la TRI-SPACE) ?

Regards,

Ralph

But if we have a doublet plus another element, then we have a triplet, no?
I confess may main interest was not getting reduced cost, but getting a doublet with the same performance as triplet, with the advantages of less surfaces, less collimation issues and less weight.
Is there any advantage (other than price) of this system over a triplet apo?
Could this technology be used for corrector plates of 12” (or larger) Cats?

I am surrounded by people who have been talking about this technology for years. I'm very eager to see what the diffractive optic does. All the ones I've seen are small and on flat surfaces.

Is this use of a kind of fresnel a similar idea?

Ok, I had to do some editing already. Please keep the discussion on topic, we are not hear to discuss the attitudes of other CN members.

I have no issue locking this thread if the name calling continues.

All these ideas are quite similar in princip - based on the ability of a DO element to correct chromatic aberration along with some other important aberrations.
