The transmitted field characters of h-SIL are affected by the material dispersion with illuminating lights of different wavelengths, The resolution, focal depth, focused intensity of h-SIL are sensitive to the change of wavelength and have a periodic oscillation whh the wavelength's change.

对应不同波长的照明光，h-S1L的材料色散作用将对其透射场特性产生影响。h-SIL的分辨率、焦深和聚焦强度对照明光的波长变化非常敏感，都随着波长的变化成周期性的振荡。
