The MR™ Series is a line of optical materials with high refractive index, high Abbe number, low specific gravity and high impact resistance. The lens material is suitable for ophthalmic lenses and is known as the first thiourethane based high-index lens material. Offered in a variety of grades, MR Series yields safe, clear and lightweight lenses for optical users.
The optical lens material is suitable for use in the development of light weight lens. The MR™ Series offers 3 different refractive index products (R.I. 1.60, 1.67, 1.74). With the inclusion of this high refractive index material, it is possible to achieve thinner lenses with the same strength as thicker lenses.
With the high refractive index and high Abbe number of these Monomers comparable optical performance to glass lenses can be achieved. In addition, glass mold-casted MR™ Series shows minimal stress-strain and the optical quality is superior to injection molded polycarbonate lens.
MR Series' good mechanical strength and stress free properties make it suitable for unique lens designs such as "Rimless frame" or "High curve lens".
The optical material's durability and good weatherability ensures that the lens can withstand high usage with minimal discoloration even after years of use. MR™ Series is compatible with a variety of coating materials and has good color tintability making it suitable for high fashion sunglasses with special color needs.
