ITO Glass Coverslips

Designed to hold specimens flat and in place, glass coverslips protect against dust and contamination through accidental contact. They also prevent contact between a microscope’s objective lens and the specimen and/or contact between a specimen and immersive liquids (water or oil, for example). The overall quality; thickness and anti-static, as well as optical properties of coverslips are of crucial importance in high-resolution microscopy.

A market leader in the manufacture and supply of a wide range of ITO glass coverslips, Diamond Coatings supply both custom and standard ITO coverslips to research institutions and universities around the world.

*About Borosilicate Glass for ITO Coverslips

A type of low soda glass, Borosilicate glass consists primarily of:

• Silica – 70%
• Boric oxide – 10%
• Sodium oxide – 8%
• Potassium oxide – 8%
• Calcium oxide – 1%

While the production of Borosilicate glass is somewhat more difficult than the manufacture of traditional glass, its superior durability makes its production highly economical.

Featuring heat and chemical resistance properties that are of excellent use for chemical laboratories; military and a variety of other uses, Borosilicate glass is (optically) crown glass with low dispersion and comparatively low (1.51 to 1.54 across visible range) refractive indices.

The thermal expansion coefficient of Borosilicate glass is very low, which also makes it a highly popular material for flat TFT screens and a range of other critical display equipment.
