流式细胞分析的照明模块

2019年4月1日 作者: IDEX Health & Science

 

如何提高流式细胞分析的吞吐量?

荧光仪器的吞吐量通常受到样品照明速度的限制。成像整个区域需要多个“步骤和拍摄”扫描,然后拼接到一起覆盖整个样品区域。

在传统的荧光系统中,有两种方法可以提高吞吐量。你可以减少曝光时间,这样你就可以走得更快,或者,你可以增加视野,这样你就可以采取较少的步骤。然而,这两种选择都需要更高的辐照度或更高的功率,这就导致了一个关键的照明难题。

选择 LED 并妥协光谱和空间亮度,或选择激光光源,但失去光束轮廓均匀性和波长可用性。

现在,你不必选择。

我们的工程师用广野照明模块解决了这个难题。在这个单一的单元中,我们通过客制化的光束成形技术来扩展光束的形状来解决均匀性问题。对于多色的应用,我们通过将特定的 LED 和激光器结合到一个模块中,完全利用了波长的可用性来满足你的波长要求。我们的广野照明模块结合 LED 和激光,以将各种光源照射到您的流式细胞样品上,从而优化性能和成本。

 

使用 IDEX Health & Science 的紧凑的、多用途广域照明模块,提高吞吐量,减少分析时间。 更多有关广野照明模块的知识,请 下载白皮书
