產品系列說明

可提供完整的計量資料
精密級非球面表面
透鏡數值孔徑為 0.66 和 0.50

TECHSPEC^®校準級非球面透鏡提供現有經拋光非球面透鏡的最佳性能和精度。這些組件提供改善的非球面面形、表面質量及中心規範，優於 TECHSPEC^®非球面透鏡，是整合到研發及OEM應用等的理想之選。這些高數值孔徑透鏡在提高微光檢測系統的效率或需緊湊光路的應用方面非常出色。

每個透鏡均編有序號，且提供完整的量測資料包。該測試資料包涵蓋Taylor Hobson Talysurf 輪廓儀上運行的薄膜測厚儀，球面干涉圖，以及直徑、中心厚度和中心定位的測試值。有關客製設計的校準級非球面透鏡和鍍膜要求或批量定價的詳細資訊，請聯絡我們的銷售部門。
