| Coating Type (膜系類型) | Properties and Application (屬性和應用) | |||||||
| Antireflection 減反膜(或增透膜) | Single Layer MgF2 (單層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. | ||||||
| (應用于材料折射率從1.45至2.4,歡迎的增透膜為可見光區(qū)的,在這一區(qū)域受入射角度變化影響較?。?/font> | ||||||||
| Multilayer "V" (多層“V"型曲線增透膜) | Used to provide low reflectance with in a narrow durable wavelength band for most laser application. Minimum reflection can be less than 0.1% | |||||||
| (可在一個狹窄的耐用波長頻帶提供很低的反射率,廣泛應用激光領域。最小反射可以少于0.1%) | ||||||||
| Broadband Multilayer(寬帶多層減反膜) | These coatings have excellent performance over a broad spectral range broadband. Coating performance is sensitive to angle of incidence. | |||||||
| (此類型膜系可以在一個比較寬的光譜范圍帶有良好的減反性能。此類型減反膜性能受入射角變化影響很大) | ||||||||
| Dual Wavelength Band(雙波長多層減反膜) | 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. | |||||||
| (在兩個間隔很寬的波長帶上,通過復合使提供更大帶寬范圍內(nèi)非常低的反射率,比如Nd:YAG激光(1064)及其二次諧波(532)。疊加得到雙波長波片) | ||||||||
