ITO Coated Glass
Capability
Diamond Coatings offer a comprehensive range of ITO coated glass types & expert guidance on suitable glass substrates for ITO slides, coverslips and many other applications. Substrates can be provided:
- Fully Dimensioned
- Radius
- Profiled with chamfer edges to suit customer requirements
Using the latest in glass processing technology, we can also provide substrates with holes and cut-outs as required. Substrates can also be supplied polished to meet specific optical and flatness requirements.
In addition to our ability to supply thermally and chemically toughened Indium Tin Oxide coated slides & coverslips, we can also offer further enhancements including anti-glare finishes and/or printed graphics/borders.
ITO Coated Glass Substrate Options
Our range of substrate options currently includes:
Soda Lime Glass & Toughened Options
The most commonly used and, due to low processing cost, most inexpensive options is Soda Lime Glass. Created by drawing glass over tanks of molten Tin, this type of glass can be supplied as standard or thermally/chemically toughened and cut to various sizes.
The air side (the side facing away from the tin during the production process) is typically both flatter & smoother than the side facing the molten tin.
Borosilicate
A low-soda type glass, Borosilicate glass primarily consists of:
- Calcium Oxide – 1%
- Sodium Oxide – 8%
- Potassium Oxide – 8%
- Boric Oxide – 10%
- Silica – 70%
Although making this type of glass is considerably more difficult than making traditional glass, it is highly economical to produce due to its superior durability. A crown glass in optical terms, Borosilicate glass offers:
- Low Dispersion
- Relatively low refractive indices (1.51 – 1.54 across the visible range)
- Chemical & heat properties of exceptional use in chemical laboratory, military and other applications
With very low thermal expansion coefficient (~3×10-6/°C at 20 °C), Borosilicate glass is a popular choice for flat TFT screens and diverse critical display equipment.
Fused Quartz & Silica
Fused Quartz and Silica glass primarily contains Silica in a non-crystalline, or amorphous, form. These glass types are manufactured using several different processes.
Fused Quartz – To produce Fused Quartz glass (which is usually transparent), high-purity naturally occuring Quartz is melted at around 2000º C within an electric (electrically fused quartz) or a gas/oxygen fuelled (flame fused quartz) furnace.
Fused Silica – Often referred to as higher standard Fused Quartz, Fused Silica is produced by melting a high-purity Silica sand feedstock within an electric furnace. The resulting material is translucent or opaque.
BK7
Widely used in high transmission displays, BK7 glass has, when uncoated, a standard optical performance of 93% (average). Application of anti-reflective coatings can further improve this transmission.
Produced in blocks, cut into required thicknesses and polished to required dimensions on both sides, BK7 is a comparatively expensive material.
Coatings & Other Options
Depending on requirements, substrates may be coated with Diamox ITO or Diamox+ Index Matched ITO and/or anti reflective coatings.
