We are experiencing some problems with horizontal high frequency banding
across our image screen when running the confocal.  The banding is a
series of light and dark bands which cut across the screen from one end
to the other.  It doesn't seem to be a result of vibration.  It could
possibly be line noise or from the laser power supply or other
electrical noise.  We have a small surge protector on the electrical
line.
 
Has anyone else experienced these problems?
