  • Choosing A Light Detector - Chapter 10 - Light

    Choosing a Detector (Chapter 10) Sensitivity Sensitivity to the band of interest is a primary consideration when choosing a detector. You can control the peak responsivity and bandwidth through the use of filters, but you must have adequate signal to start with. Filters can suppress out of band light but cannot boost signal.
