    • In one general aspect, a particle characterization instrument is disclosed that includes a first spatially coherent light source with a beam output aligned with an optical axis. A focusing optic is positioned along the optical axis after the coherent light source, and a sample cell is positioned along the optical axis after the focusing optic. The instrument also includes a diverging optic positioned along the optical axis after the sample cell, and a detector positioned outside of the optical axis to receive scattered light within a first range of scattering angles from the diverging optic. In another general aspect, an instrument can direct at least a portion of a first beam and at least a portion of a second beam along a same optical axis and a can receive scattered light from the sample cell resulting from interaction between the sample and either the first beam or the second beam.
    • 在一个一般方面,公开了一种粒子表征仪器,其包括具有与光轴对准的光束输出的第一空间相干光源。 在相干光源之后,聚焦光学器件沿着光轴定位,并且在聚焦光学器件之后沿着光轴定位样品池。 该仪器还包括在样品池之后沿着光轴定位的发散光学器件,以及位于光轴外侧的检测器,以在来自发散光学器件的散射角度的第一范围内接收散射光。 在另一个总体方面,仪器可以引导第一光束的至少一部分和沿着相同光轴的第二光束的至少一部分,并且可以从样品与第二光束之间的相互作用接收来自样品池的散射光 第一光束或第二光束。
