產品系列說明

專為1倍放大倍率設計
精密級非球面面形誤差
提供10～50mm直徑

TECHSPEC^® 1550nm 精密近红外（NIR）非球面透镜设计波长为 1550nm，以消除近红外的球面像差。1550奈米雷射器通常用於電信、雷射雷達及其他需要人眼安全設計特徵的應用。這些非球面透鏡由S-TIH6或N-SF6基片製造，並透過數控（CNC）工藝進行拋光，在整個近紅外光譜中實現了高精度性能。這些透鏡具有 0.4λ RMS 非球面面形誤差，是需要球差校正應用（包括成像和雷射聚焦應用）的理想選擇。TECHSPEC^® 1550nm 精密近紅外 (NIR) 非球面透鏡設計有低數值孔徑版本，用於需要保持光束形狀的應用，也有高數值孔徑版本，用於聚光應用。如需客製設計的數控（CNC）拋光非球面透鏡，請聯絡我們。
