摘要
指出激光共焦生物芯片扫描仪的光束分离器设计最终影响系统分辨率,简要给出了采用波长光束分离器和几何光束分离器的优缺点为满足仪器扫描分辨率和灵敏度这对互相受牵制的因素,系统地分析了几何光束分离器中,采用的反射镜孔径的定量分析计算方法所得的结果对几何光束分离器的设计和性能的评价有重要的意义。
The influence of the design of beamsplitter in confocal biochip scanner upon system′s resolution is pointed out, then the two designs adapting dichroic or multichroic beamsplitter and geometric beamsplitter are listed and compared with each other briefly. A quantitive calculative method of the hole diameter of reflector in geometric beamsplitter, according with the demand of the scanning resolution and sensitivity a pair of counteractive factors, is analysed mainly. The result is very useful for the design and characteristic evaluation of geometric deamsplitter, and the experiment results are given.
