These terms are usually for electron microscopy sections or plastic light
microscopy sections. 

In the EM lab a thick section is a one-micron plastic section for light
microscopy of EM -embedded blocks. It could also be called semi-thin.

Thin, or Ultra thin sections are terms used for the sections for use in the
EM., ie, 400A to 800A in thickness.


"Thin" can also be used for light microscopy plastic section of 1um in
thickness. They are thin in relation to paraffin sections.

Subject: [Histonet] semithin-ultrathin


Hi,
I've searched in the internet for a list that explains the thickness of
semi-, ultra-, thin, thick sections. But I failed. My knowledge is only
approximately. 
Perhaps someone can help me?
