TECHSPEC® 高精度非球面透镜保证非球面面型误差优于 λ/40 。这些非球面透镜通过精密的磁流变抛光 (MRF) 而实现，能提供直径介于 15 至 50mm 的高数值孔径，非常适用于各种成像和微光应用。提供适用于可见光和近红外 (NIR) 波长的宽带增透 (BBAR) 膜选项。 每个 TECHSPEC 高精度非球面透镜都经过单独测量。无镀膜版本提供 3D 表面轮廓。如需为特定 Nd:YAG 激光波长而设计的衍射极限非球面透镜，请参阅我们的 TECHSPEC 高精度激光级非球面透镜。


  • 具有高精度非球面表面

  • 未镀膜透镜带有 3D 表面轮廓

  • 可选未镀膜和反射比 <0.25% 的 V 型镀膜
