    • An optical lens system that focuses both a first band of wavelengths and a second band of wavelengths onto a common focal plane. In some cases, the lens system includes a first region for focusing a first band of wavelengths onto a focal plane, and a second region for focusing a second band of wavelengths onto the same focal plane. Depending on the wavelengths and materials involved, the first region may or may not focus the second band of wavelengths onto the focal plane, and in some cases, may or may not even transmit the second band of wavelengths to the focal plane. Likewise, the second region may or may not focus the first band of wavelengths onto the focal plane, and in some cases, may or may not even transmit the first band of wavelengths onto the focal plane, but this is not required. In some embodiments, an additional lens may be provided between the lens system and the common focal plane to help focus the first band of wavelengths and the second band of wavelengths onto the common focal plane. The additional lens may be made from a material or material system that transmits and focuses both the first band of wavelengths and the second band of wavelengths.
    • 一种将第一波长波段和第二波长带聚焦在公共焦平面上的光学透镜系统。 在一些情况下,透镜系统包括用于将第一波长带聚焦到焦平面上的第一区域和用于将第二波长带聚焦到同一焦平面上的第二区域。 取决于所涉及的波长和材料,第一区域可以或可以不将第二波长带聚焦到焦平面上,并且在一些情况下,可能甚至不会将第二波长带透射到焦平面。 类似地,第二区域可以或可以不将第一波长带聚焦到焦平面上,并且在一些情况下,可能甚至不会将第一波长带传播到焦平面上,但是这不是必需的。 在一些实施例中,可以在透镜系统和公共焦平面之间提供附加透镜,以帮助将第一波长波段和第二波长带聚焦到公共焦平面上。 附加透镜可以由材料或材料系统制成,该材料或材料系统透射和聚焦第一波长波段和第二波长波段。

    • A method and apparatus for enabling chemical identification of individual particles, cells of molecules by obtaining a Raman spectrum of a particle, cell or molecule as it flows past a sensing point in a flow cytometer. The particles, which may be cells or molecules, are associated with a suitable noble metal colloid or colloidal aggregate. Cellular particles may be associated with gold or silver colloidal particles by ultra-sonic sonification while in a sample preparation reservoir containing the gold or silver colloidal suspension. The colloid associated particles are then hydrodynamically focused into a single file by a fluid control module. The surface-enhance Raman Spectrum of individual particles are obtained by illuminating the particle with a laser as the particle flows past a sensing point and gathering the light that is non-elastically scattered (Raman scattered) by the particle. The surface-­enhanced Raman spectrum is then analyzed to identify the particle.
    • 一种方法和装置,用于通过在流式细胞计数器中流过感测点时获得粒子,细胞或分子的拉曼光谱,从而能够化学鉴定单个颗粒,分子细胞。 可以是细胞或分子的颗粒与合适的贵金属胶体或胶体聚集体相关联。 在含有金或银胶体悬浮液的样品制备储存器中,细胞颗粒可以通过超声波超声处理与金或银胶体颗粒结合。 然后通过流体控制模块将胶体相关颗粒流体动力聚焦成单个文件。 当颗粒流过感测点并通过颗粒收集非弹性散射(拉曼散射)的光时,通过用激光照射颗粒来获得单个颗粒的表面增强拉曼光谱。 然后分析表面增强拉曼光谱以鉴定颗粒。
