瑞聲科技業界首創WLG三合一"超光棱鏡"上市
綜合vivo和瑞聲科技官方消息,近日vivo發佈的高端旗艦手機 X200 Ultra,創新使用了業界首創的WLG三合一超光棱鏡(power prism)。
該產品由vivo和瑞聲科技聯合研發,依託WLG技術一體成型,具有精度更高、性能更好、穩定性更強、輕薄化設計等特點。進光量相比上一代產品大幅提升38%,防抖能力增強41%。

與傳統平面棱鏡或鏡片與棱鏡的膠合結構相比,該產品最大革新點在於,實現了非球面+棱鏡+球面的一體化融合。據瑞聲科技官微介紹,這顆超光棱鏡結構非常複雜,需要在棱鏡入射面和出射面整合凸鏡和凹鏡,製造難度極大。而WLG技術可實現一體加工成型,無需膠合,流程簡單,且可滿足高階長焦鏡頭的精度需求。陣列式排布的生產方式和結構自由度,也更適合規模生產的需求。
據瞭解,WLG是瑞聲科技全球獨有的晶圓級玻璃製造工藝,除了非球面棱鏡外,還可用來生產非球面鏡片、自由曲面鏡片、陣列透鏡、準直透鏡等多類型產品。在光學性能、光學精度、鏡片結構、鏡片厚度和極致性能等方面較其他玻璃成型技術具有明顯優勢。
據券商最新研報,今年瑞聲科技WLG產品的出貨量將同比增長數倍至千萬級,將廣泛運用在智能手機、汽車、機器人等領域。基於WLG技術設計製造的WLG玻塑混合鏡頭已成爲攝像頭行業重要發展趨勢,將對目前以塑膠鏡片爲主流的光學行業及應用領域帶來改變。
