Scanning electron microscope

Tags:
  1. Nov 5, 2013 #1
    Hi,
    I am working with a scanning electron microscope with the SED and it works fine. I have tried on several occasions to use the BSED without any success. All I get is a very faint dark image. Would you be able to give me some advice as to where I am going wrong?
    Thanks in advance

    Have you tries hitting the auto-contrast/brightness button???

    Back-scattered images can be difficult to generate, and the signal depends heavily on the atomic weight of your sample, detector position, as well as general good imaging practices. Also, doped silicon BSE detectors tend to be slower than SE detectors, so using slower scan rates could help
