适合微光探测应用，光电倍增管（PMT）提供极高的灵敏度和超快速响应。
Suitable for low-light-level detection applications, the photomultiplier tube (PMT) provides extremely high sensitivity and ultra-fast response.
用CCD检测仪取代了常用的光电转换器件——光电倍增管，通过与光栅结合实现了光谱的快速分析。
The CCD detector was used to take place of the photomultiplier which was widely used as the optical-electrical converter, and the fast analysis of the spectrum was realized by incorporating a grating.
