[wilddevil]

I have lately received a new software update of the MR. Blue edging and I have seen a new logo on the type lens category.
The repp said something about tribird...did u hear something about this kind of marerial?

It's like those composite materials (thiner than 1,74 as) but this one is unique for its strength and is a little light.

I hinted to it's arrival last month in a post:

Look to higher index impact resistant lenses in the near future as the technology to nitrogen enrich urethane lenses is extended to other higher index materials. Tribrid will be a poly killer if the cost is kept appropriate.

from reading of the links, it seems like a (1.60 + trivex) with 41 Abbe; or a better poly in short

This is all the info you need.

Daddy likes. I wonder how thin it can be surfaced. 1 mm?

Who manufacturers that lens?

[jonah]

It is available from at least two labs in Canada, Nova labs and Oculab.

[Fezz]

Do you work for Essilor Jonah?

Is this a different material than the Tribrid that I referenced?

If so, care to elaborate on the differences?

[finefocus]

Also, this/these material(s) are "high impact resistance", but how high? As high as poly or trivex? OK for sports glasses or kids?

[jonah]

No I do not work for Essilor or any of its affiliates.
I know as much as the link can describe , plus I have tried them and they seem to be true to their description.
Anyway, how does Essilor come into this? besides for the fact that they seem to be involved in most lens manufacturing.

The machine in question from the original poster is an Essilor product and they released a new materials option on this machine before this lens was available here in the US.

Also your lens described in earlier posts is not Tribrid, The index is lower but the abbe is higher. My issue would be the level of support for this material. Is it here today gone tomorrow? I know that with PPG's backing and other industry power players behind Tribrid it is here to stay and those that stay ont he forefront should start sucking in all the information they can get now.

The material that Jonah referenced is, in fact, not the same as Tribrid.

Thank you for the confirmation.


Is essilor going to release their flagship lens designs in this newer material? That's the question on my mind.

I don't think any material will be able to deal the with heat issue 1mm CT, thinner lenses simply cause problems in AR degassing (heating), even poly. Not all of them fail of course, but you get a higher % of abberation and warping the thinner you go as they heat and cool, and the material is not able to transistion well. I don't recommend going below 1.3 mm CT for any material.

[Uilleann]

To be perfectly clear, there are indeed two different materials referenced above:

1 - "Tribrid" from PPG which states the following values: 1.60 IR, 1.23 SG, 41 Abbe
&
2 - "Nova-Quatrex" from Polyoptics International showing: 1.58 IR, 1.25 SG, 48 Abbe

Both state 100% UVA-B, and impact resistance equal to or exceeding poly/Trivex.

I assume the PPG offering will eventually be much more readily available in the US/Canada, although the Polyoptics product is certainly superior in regards to Abbe on paper. Cost would be the #1 concern I have, followed very closely by product/design availability. Time will tell if either of these catch on with the mainstream.

no dear i never heard about this material whats this????

[heykevin]

Let me know as u'll get any information

oops, wrong thread
