產品系列說明

  • [λ/40 非球面表面容差 (RMS)
  • 保證 0.8 以上的 Strehl 比
  • 雷射光 V-Coat,反射率低於 0.25%
  • 整體鏡頭設計均針對雷射波長最佳化

TECHSPEC® λ/40 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 λ/40 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。
