MR-10 monomer manufacturer?

**Iakwin** · 06-12-2005, 04:05 AM

Dear All,

Do you know who is doing the monomer MR10?

**AWTECH** · 06-12-2005, 12:51 PM

I do not know if you mean who is making lenses with MR-10 or the actual chemical company. There a number of lenses made with MR-10. Seiko, Shamir and I think now Yonger offers lenses in MR-10.

The chemical company is Mitsui Chemical of Japan.

Do they also make the MR-?, 1.60 index material?? What about other high index, 1.70 and 1.74??

Aren't Essilor and Nikon also M-10 along with Sola?

As AWTECH noted, MR-10 is made by Mitsui Toatsu in Japan, as is any high-index material that uses the prefix "MR," including MR-6 (1.6), MR-7 (1.66), and MR-8 (1.6). Seiko uses MR-10 for their 1.67 high-index lenses; most manufacturers use MR-7.

Essilor and Sola both use the MR-7 monomer for their 1.67 products. I also know Signet Armorlite uses the MR-7 for their 1.67.

Dear AWTech,

I would like to know the raw material of MR10. Do you have the technical sheet of this material? Thanks.

SOLA actually uses MR-10 for all of our newer products.

**jjbons** · 05-11-2006, 10:20 AM

HOYA also uses MR10 for its 1.67 lenses.

**Brando** · 05-11-2006, 03:26 PM

Also X-Cel Optical's SF 1.67's are made out of the MR-10 material.

Which one are you using for Finalite - since this has a good abbe?

Whats the difference between MR-7 and MR-10? Are data sheets available on all the MR materials?

**Darryl Meister** · 05-30-2006, 11:41 AM

MR-10 is a newer, improved version of MR-7. MR-10 has greater thermal resistance than MR-7, making it less susceptible to heat distortion during the surfacing and coating processes. The MR-10 substrate also demonstrates improved flexural stability and tensile strength.
