Mitsui Chemicals develops Diffrar™ optical polymer wafer for AR glasses

Mitsui Chemicals, Inc. is advancing the development of Diffrar™ polymer wafers for waveguides used in augmented reality (AR) glasses, with a view to expanding the augmented and virtual reality markets. The company has now developed the world's first* optical polymer wafers with refractive indices of 1.67 and 1.74 in a 12-inch size, specifically for AR glasses.

Equipped with outstanding optical properties, including a high refractive index of 1.67 or higher and extreme flatness, Diffrar™ optical polymer wafers offer users of AR glasses a wider Field of View (FOV). In addition, the use of Mitsui Chemicals proprietary polymer allows Diffrar™ to achieve greater impact resistance, making devices safer and lighter than glass, and thereby enabling users to wear them comfortably for extended periods of time.
