       减反膜(或增透膜)
      Single Layer MgF2
      (单层MgF2)
      Applied to materials with refractive indices from 1.45 to 2.4. The most popular antireflection coating for visible. They are insensitive to change in incidence angles.
      (应用于材料折射率从1.45至2.4,最受欢迎的增透膜为可见光区的,在这一区域受入射角度变化影响较。
      Multilayer "V"
      (多层“V"型曲线增透膜)
      Used to provide low reflectance with in a narrow durable wavelength band for most laser application. Minimum reflection can be less than 0.1%
      (可在一个狭窄的耐用波长频带提供很低的反射率,广泛应用激光领域。最小反射可以少于0.1%)
      Broadband Multilayer(宽带多层减反膜) These coatings have excellent performance over a broad spectral range broadband. Coating performance is sensitive to angle of incidence.
      (此类型膜系可以在一个比较宽的光谱范围带有良好的减反性能。此类型减反膜性能受入射角变化影响很大)
      Dual Wavelength Band(双波长多层减反膜) Offer very low reflectance at two widely spaced wavelengths, such as Nd:YAG Laser (1064) and its second harmonic (532) . Tempotec makes this a double wavelength waveplate.
      (在两个间隔很宽的波长带上,通过复合使提供更大带宽范围内非常低的反射率,比如Nd:YAG激光(1064)及其二次谐波(532)。叠加得到双波长波片)

      AR coating sample curves
      单层MgF2,在波长400 ~ 700 nm(入射角为0),平均反射率 < 2%

      单波长减反膜在波长为1064nm(入射角为0时),反射率R < 0.25%

      宽带多层减反膜,在420nm~700nm范围内(入射角度为0)平均反射率 < 1.0%

      双波长剁成减反膜在532nm~1064nm(入射角度为0)时平均反射率 < 0.25%
