Insights

  • Mitsui Chemicals has developed the world's first 12-inch Diffrar optical polymer wafers for AR waveguides.
  • With refractive indices of 1.67 and 1.74, they enable a wider field of view in AR glasses.
  • The proprietary polymer offers high flatness, impact resistance, and lighter weight than glass.
  • Multiple wafer sizes improve design flexibility and manufacturing efficiency.
Mitsui Chemicals, Inc. (Tokyo: 4183; President & CEO: HASHIMOTO Osamu) 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.

Available in 1.67 and 1.74 refractive indices, the product lineup features 6-inch (for sample testing only), 8-inch (200mm) and 12-inch options (300mm), providing a wider variety of options for AR Optical Designers and increasing efficiencies in their manufacturing processes.
