公版繞射光學元件

迪鵬提供多種公版繞射元件（衍射光學元件）、光柵鏡片，圖案包括亂點、圓形點、平行線、十字線、瞄準線、方格、同心圖案、長方框、直線、規則點等等，這些標準產品能為客戶省下開發初期的模具費用，降低門檻、加速產品開發，為客戶的產品增加商品價值。

十字線、一字線、同心圓等圖案，常作為瞄準、定位等應用；瞄準線( ViewFinder) 則用於Barcode reader 瞄準條碼用；亂點圖案則常用於結構光(strucutred lighting)或雙目結構光、3D sensing、人臉識別( Face ID、 刷臉支付) 等應用。

標準基材是 0.188mm 厚的PET，標準尺寸為直徑 5mm 或 5x5 mm， 某些產品有0.3mm厚玻璃，或1mm 厚的PMMA 選項，若您需要客製化的切割尺寸，請您下單前先詢問。若應用波長與原先設計波長不同，偏離設計波長越遠，中心零階會越高，繞射圖案扭曲變形會越嚴重。

所有的公版繞射元件( Diffracitve Optical Element)，都能組裝成DOE 雷射模組出貨，可搭配的雷射模組波長和功率請參考下表。
