[{"type":"text","content":"\nA Major Optics Breakthrough – Enables Super-Compact, Lightweight, Stylish VR Glasses\n\n WESTBOROUGH, Mass.--(BUSINESS WIRE)--\nKopin® Corporation (NASDAQ: KOPN), a leading developer and provider of high-resolution microdisplays and display subassemblies for defense, enterprise, consumer and medical products, announced today it has succeeded in developing all-plastic Pancake® optics with breakthrough performance for virtual reality (VR), augmented reality (AR) and mixed reality (MR) applications. This is a major advance and believed to be the first all-plastic Pancake optics in the world with excellent performance. Kopin has applied for three patents on the design, manufacturing processes and system utilization of all plastic Pancake optics, and expects additional filings to follow.\nThis press release features multimedia.

However, previous Pancake optics needed at least one spherical glass lens to avoid image artifacts caused by birefringence of the plastic material, but this glass lens added both weight and cost to the lens system. Kopin’s new all-plastic Pancake optics with all aspherical lenses (compared to previous Pancake optics using spherical glass lens) substantially reduce the weight and thickness while significantly improving the image quality – all at a lower cost.\n\nPancake optics work by reflecting light back and forth within the optical system. In order to reflect the light correctly and avoid image artifacts, the polarization state of light must be precisely controlled. Unfortunately, plastic materials usually have large birefringence that disturbs the polarization state, and until now all-plastic lenses have not been able to overcome the disturbance of the polarization state.\n\nKopin’s all-plastic two-element Pancake optics have virtually no birefringence. At the core of the technology is a patented aspherical optical lens design that achieves great image performance and processing methods to preserve the negligible birefringence of a special plastic material with unique characteri...
