An apparatus for illuminating a sample comprises a sample plane (205) having an illumination region onto which the sample is arranged, an excitation light unit including at least one light source (201) for generating excitation light, a lens unit having a micro lens array (206) comprising a plurality of lenses arranged in a two dimension arrangement for receiving the excitation light and generating illumination light that is directed towards the illumination region, wherein the lens unit produces homongeneous illumination light to be projected on the illumination region with a high illumination efficiency. The apparatus for illuminating may be comprised in an imaging system, said imaging system further comprising a detector for detecting signals from the sample, thereby acquiring an image, such as a fluorescence image, of the sample, focusing means for focusing the signals on the detector, and a processor for receiving data from the detector.
一种用于照亮样品的装置包括一个样品平面(205),该样品平面具有一个照亮区域,样品被放置在该照亮区域上;一个激发光单元,该激发光单元包括至少一个用于产生激发光的光源(201);一个透镜单元,该透镜单元具有一个微透镜阵列(206),该微透镜阵列包括多个透镜,这些透镜以二维排列方式排列,用于接收激发光并产生射向照亮区域的照亮光,其中透镜单元产生同调照亮光,以高照亮效率投射到照亮区域上。用于照明的装置可包括一个成像系统,所述成像系统进一步包括一个检测器,用于检测来自样品的信号,从而获取样品的图像,例如荧光图像;聚焦装置,用于将信号聚焦到检测器上;以及一个处理器,用于接收来自检测器的数据。
