    • A system, apparatus and method for spatially distributed, spectrally neutral optical attenuation. One embodiment of the apparatus can include: an attenuator fin plate; a set of attenuator fins, wherein each of the fins is operably coupled to the fin plate at a preset fin angle to the fin plate normal such that the attenuator fins maintain their position relative to the fin plate as the fin plate moves; and a motor for rotating the fin plate a set angular distance around an axis of rotation, wherein the axis of rotation is at a preset fin plate angle to a light beam direction of travel and wherein the attenuator fins block varying amounts of the light beam as the fin plate is rotated through the set angular distance. The attenuator fin plate and attenuator fins can be a single, integral component, wherein the attenuator fin plate is etched and stamped to form the attenuator fins, or separately formed components that are attached, for example, to a separate frame. The embodiments of the attenuator of this invention can be configured for use within an ophthalmic high brightness illumination system.
    • 用于空间分布,光谱中性光衰减的系统,装置和方法。 该装置的一个实施例可以包括:衰减器翅板; 一组衰减器翅片,其中每个翼片以与翅片板法线成预定的翅片角度可操作地联接到翅片板,使得当翅片板移动时,衰减器翅片相对于翅片板保持它们的位置; 以及电动机,用于使所述翅片板围绕旋转轴线旋转设定的角度距离,其中所述旋转轴线相对于光束行进方向处于预设的翅片板角度,并且其中所述衰减器散热片将不同量的光束阻挡为 翅片板旋转设定的角度距离。 衰减器翅片板和衰减器翅片可以是单一的整体部件,其中衰减器翅片板被蚀刻和冲压以形成衰减器翅片,或者单独形成的部件,例如附接到单独的框架。 本发明的衰减器的实施例可被配置为在眼科高亮度照明系统内使用。
