Abstract: High numerical aperture collection optics for particle analyzers may include an ellipsoidal reflector or an ellipsoidal reflector in combination with a spherical reflector, and may efficiently collect light scattered or emitted by particles in a sample stream and then couple that collected light into a lower numerical aperture portion of the instrument's optical detection system, such as into an optical fiber for example. The reflectors may be integrated with a flow cell through which the sample stream passes, or may be separate components arranged around a flow cell or, in instruments not employing a flow cell, arranged around a sample stream in air. Refractive beam steering optics may allow multiple closely spaced excitation beams to be directed into the sample stream at low angles of incidence. The collection optics and refractive beam steering optics may be employed separately or in combination with each other.
Abstract translation: 用于粒子分析器的高数值孔径采集光学器件可以包括椭球反射器或与球形反射器组合的椭圆反射器，并且可以有效地收集由样品流中的颗粒散射或发射的光，然后将收集的光耦合到较低的数值孔径部分 的仪器的光学检测系统，例如成为光纤。 反射器可以与样品流通过的流动池一体化，或者可以是布置在流动池周围的分离的组件，或者在不使用流动池的仪器中，布置在空气中的样品流周围。 折射光束转向光学器件可以允许多个紧密间隔的激发光束以低入射角被引导到样品流中。 收集光学器件和折射光束转向光学元件可以单独使用或者彼此组合使用。
