    • A surgical microscopy system having an illumination system is provided. The illumination system comprises a xenon gas discharge lamp and a spectral filter which is optionally positionable into an illumination beam path of the surgical microscopy system and removable from the same. The spectral filter substantially exhibits, in a wavelength range between 400 nm and 700 nm, a transmission increasing from about 0.12 to 1 having a gradient between 0.025/nm and 0.0035/nm, in particular 0.00293/nm. Thus, the illumination system is enabled to provide light having two different spectral characteristics which is advantageous in particular for imaging structures in the human eye scattering to a different degree.
    • 提供具有照明系统的手术显微镜系统。 照明系统包括氙气体放电灯和光谱滤光器,其可选地可定位到手术显微镜系统的照明光束路径中并且可从其移除。 光谱滤光器在400nm和700nm之间的波长范围内基本上表现出具有0.025 / nm至0.0035nm之间的梯度,特别是0.00293 / nm的梯度的透射率从约0.12增加到1。 因此,照明系统能够提供具有两个不同光谱特征的光,这对于人眼中的成像结构在不同程度上是有利的。
