產品概覽

適用 Nd:YAG 雷射波長優化的基材形狀和鍍膜
高精密非球面面形
斯特利爾比 > 0.8

TECHSPEC^® 高精密雷射級非球面透鏡是以精密的磁流變拋光 (MRF) 技術進行拋光，打造超平順的非球面表面，提供 λ/40 RMS 的非球面表面容差。本系列非球面透鏡以此超級拋光製程實現無像差的非球面表面，可在設計波長提供繞射極限效能。高效能雷射光V-Coat 可在這些非球面透鏡於其 Nd:YAG 波長使用時盡可能減少反射。TECHSPEC^® 高精密雷射級非球面透鏡採用專為其雷射波長設計及成形的基材，以便針對雷射波長最佳化整體透鏡設計，不只是抗反射鍍膜而已。供應標準大型尺寸搭配熔融石英製造的 f/2 設計。
