ÍÆ¼ö³æ³æ¿ÉÒÔÔĶÁ 1.Thin-film optical filter µÚÈý°æ 2.Design of optical interference coatings_ALFRED THELEN 3.¹âѧ±¡Ä¤²ÄÁϵÄÀíÂÛÓëʵ¼ù£¨µÂ¹ú£©_olaf stenzel_¹ú·À¹¤Òµ³ö°æÉç 4.ÏÖ´ú¹âѧ±¡Ä¤¼¼Êõ_ÌÆ½ú·¢ ÀïÃæÓÐÌâÖ÷ÏëÒªµÄ´ð°¸¡£ Âó¿ËÀ͵Â˵Ã÷ÊéÊÇÕâô˵Ã÷µÄ£º Layer thicknesses may be specified in four ways. Thicknesses may be either full-wave optical thickness (FWOT) or quarter-wave optical thickness (QWOT) or geometrical or physical. Physical thickness is just the thickness of the film as it would be measured by a ruler calibrated in physical thickness units, nanometres unless they have been changed by the user. In interference calculations the most important quantity associated with a layer is its effect on the optical phase of light that traverses it. The phase change depends on the optical path and the vacuum wavelength. Full-wave Optical thickness, therefore, is the physical thickness multiplied by the refractive index of the material (that is the optical path) and divided by the reference wavelength. Because of its fundamental role in calculations, it is frequently used in preference to the other thickness conventions. QWOT thickness is another type of optical thickness. 1 QWOT is equal to 0.25 optical thickness units. Geometrical thickness is the ratio of physical thickness to reference wavelength. ![]() ¾Ù¸öÀý×Ó£º One of the reasons we often use the ratio of the thickness of a layer to a reference wavelength is that dimensionless quantities are usually to be preferred over dimensionedones with units. Many of the layers in the designs considered so far have optical thicknesses (FWOT) of 0.25. This means that the optical path for one traversal is one quarter of a vacuum reference wavelength. The material for one layer, listed as Na3AlF6,is cryolite or Na3AlF6, and the refractive index of this material is shown as 1.35. This is the value at the reference wavelength which is 510nm in this case. We can tell that the geometrical thickness would be 0.25/1.35 that is 0.185185. Physical thickness would be 94.444nm. |
