    • An illumination device for an optical imaging apparatus, such as a microscope. The illumination of a slide specimen is achieved when divergent light for a point light source or a plurality of point light sources illuminate the specimen converging at high angles at equal brightness across all angles. The user of divergent light cancels the cosine distributed gradient effect (Lambert's cosine law) to effectively create a substantially evenly distribution of light. The placement of diffractive or diffusive film under the specimen causes the light to converge at high angles onto the specimen. The light from the point light source can be further diffused by passing it through a column having its interior coated with a non-diffractive material adapted to widely scatter the light.
    • 一种用于光学成像装置的照明装置,例如显微镜。 当用于点光源的发光或多个点光源照射以各角度相等的亮度以大角​​度会聚的样本时,实现滑动样本的照明。 发散光的用户消除余弦分布梯度效应(Lambert余弦定律),以有效地创建基本均匀的光分布。 衍射或扩散膜在试样下的放置导致光以高角度会聚在样品上。 来自点光源的光可以通过使其穿过其内部涂覆有适于广泛散射光的非衍射材料的色谱柱而进一步扩散。
