產品概覽

具有低散射的 P4 級表面粗糙度
具有雷射等級為 10-5 的表面質量
精密 RMS 非球面形狀誤差

TECHSPEC® 低散射非球面透鏡是高品質的 CNC 拋光非球面透鏡，具有符合ISO 10110-8 P4級標準的表面粗糙度和10-5的表面質量。P4級表面粗糙度標準規定了每 10mm 取樣長度的微缺陷需少於3個，是 ISO 10110-8 所列出的光滑表面標準的最高級別。較低的表面粗糙度和10-5的表面品質使得聚焦或準直雷射時的散射率非常低。此外，還可以根據應用要求提供高雷射損傷閾值鍍膜版本。TECHSPEC® 低散射非球面透鏡是高功率雷射應用的理想選擇，適合應用於低散射最為重要的計量及航空太空行業。
