歌爾光學於SPIE XR盛會首發50°視場角碳化矽光波導

當地時間1月20日，在美國舉辦的國際XR行業頂級會議SPIE AR|VR|MR上，歌爾光學攜系列前沿光學解決方案亮相，並全球首發其突破性產品——50°視場角碳化矽刻蝕全彩光波導顯示模組F50Se。

長期以來，AR光波導的視場角受限於玻璃基底材料的折射率。歌爾光學透過採用折射率高達2.65的碳化矽基底，從材料源頭突破了物理限制，使單片全彩波導實現50°大視場角成為可能。同時，針對碳化矽極難加工的挑戰，公司創新應用乾式蝕刻工藝，將波導整體反射率降至5%以下，有效解決了殘影與彩虹紋等行業長期存在的問題。該模組配合微型光機，可實現1500尼特以上的入眼亮度，為大視野AR觀影與互動應用提供了核心硬體基礎。

除重磅新品外，歌爾光學還展示了覆蓋多元場景的完整產品矩陣：

• F30Se：極致輕薄的碳化矽模組
• F15Pi：適用於全天候佩戴的樹脂光波導模組
• F25Ge：專為戶外強光環境設計，峰值亮度達4200尼特
• 最新Pancake模組：在顯著壓縮厚度的同時，實現85.5°大視場角與近視屈光調節功能，為頭顯設備輕薄化提供了具體可行路徑

當前，XR產業正處於向消費市場普及的關鍵階段，顯示性能與設備形態仍是核心制約因素。歌爾光學透過此次展示的系統性解決方案，展現了其在材料、工藝與設計上的整合創新能力，旨在推動AR/MR設備在娛樂、辦公、工業等更多場景中實現高效、舒適的應用。未來，公司表示將持續聚焦核心技術研發，推動光學模組向更輕薄、更清晰、更普及的方向演進。

Goertek Optics Debuts 50° FOV Silicon Carbide Waveguide at SPIE XR Event
At the SPIE AR|VR|MR conference, a premier international XR industry event held in the United States on January 20 (local time), Goertek Optics showcased a range of cutting-edge optical solutions and globally debuted its breakthrough product: the 50° field-of-view (FOV) silicon carbide etched full-color waveguide display module, the F50Se.

For years, the FOV of AR waveguides has been limited by the refractive index of glass substrate materials. By adopting a silicon carbide substrate with an ultra-high refractive index of 2.65, Goertek Optics has overcome this physical limitation at the material level, making it possible to achieve a 50° large FOV with a single full-color waveguide. To address the challenges of processing silicon carbide, the company innovatively applied a dry etching process, reducing the overall waveguide reflectivity to below 5% and effectively resolving persistent industry issues such as ghosting and rainbow artifacts. When paired with a micro-projection engine, the module achieves an eye-facing brightness of over 1,500 nits, providing core hardware support for large-field AR viewing and interactive applications.

Beyond this major new product, Goertek Optics also showcased a complete product matrix covering diverse scenarios:

• F30Se: An ultra-lightweight silicon carbide module
• F15Pi: A resin waveguide module designed for all-day wear
• F25Ge: Engineered for outdoor high-brightness environments with a peak luminance of 4,200 nits
• Latest Pancake module: Achieves an 85.5° large FOV and diopter adjustment while significantly reducing thickness, offering a practical path toward lighter and thinner headset designs

As the XR industry reaches a critical stage of consumer market adoption, display performance and device form factors remain core constraints. Through this demonstration of systematic solutions, Goertek Optics highlights its integrated innovation capabilities in materials, processes, and design, aiming to enable more efficient and comfortable applications of AR/MR devices across entertainment, office work, industrial, and other scenarios. Moving forward, the company stated it will continue to focus on core technology R&D, driving optical modules toward thinner, clearer, and more accessible solutions.

Summary:
At SPIE XR, Goertek Optics unveiled the F50Se, a 50° FOV silicon carbide waveguide module delivering 1,500+ nits brightness, eliminating ghosting and rainbow artifacts. This breakthrough advances AR optics toward wider, clearer, and more practical applications.
