18X18 COVERGLASS #1.5 10 OZ (ESCO) - (0.17 mm thickness).
Microscope cover glass is a very thin square piece of glass that is placed over a drop of liquid on a microscope slide. Because of surface tension, the liquid drop alone tends to sit in a thick dome. With a cover glass in place, the drop is flattened out, allowing the analyst to focus with high power very close to the specimen. The cover glass also confines the specimen to a single plane which reduces the amount of focusing necessary. The cover glass also protects the objective lens from immersion into the liquid.
#1.5 cover glass is recommended for oil immersion or high resolution work.
