Industry leading ITO glass supplier Diamond Coatings supply ITO conductive glass on a range of substrates. Here are some of our substrate options.
ITO Conductive Glass Substrates
BK7 – Boasting an uncoated standard optical performance (average) of 93% (which can be further improved by applying anti-reflective coatings), BK7 is a glass that is used widely for applications involving high transmission displays.
Comparatively expensive, this glass is produced in blocks and cut down to required thicknesses. Specific required dimensions are then achieved by polishing (both sides).
Fused Silica & Quartz – Primarily containing amorphous (non-crystalline) silica, fused silica & quartz are produced using different processes:
- Fused Silica, which is frequently also known as “higher standard fused quartz”, is manufactured by silica sand feedstock of high purity being melted within electric furnaces, with the resulting material being opaque or translucent.
- Fused Quartz, a glass that is usually transparent, is produced by melting naturally occuring high-purity quartz within electric or oxygen/gas fuelled furnaces (i.e. electrically or flame fused quartz) at temperatures raging around 2000º C.
Borosilicate – This low-soda type of glass consists primarily of:
- 1% Calcium Oxide
- 8% Sodium Oxide
- 8% Potassium Oxide and
- 10% Boric Oxide
- 70% Silica
While it is considerably more difficult to produce than traditional glass, Borosilicate class boasts a superior durability that makes its production highly economical. In optical terms, this is a “crown glass” that offers:
- Relatively low (1.51 to 1.54 across the visible wavelength range) refractive indices
- Low Dispersion
- Heat and chemical properties that are of exceptional use in military, chemical laboratory and many other applications
Its thermal expansion coefficient of ~3×10-6/°C at 20 °C is also very low, making this glass type a highly popular choice for a diversity of critical display equipment and TFT flat screens.
Soda Lime Glass/Toughened Options – Low processing costs make soda lime (or soda lime float) glass our most inexpensive and most commonly utilised substrate option.
Produced by glass being drawn over molten tin tanks (typically resulting in the upper – air-facing – side of the glass being both smoother & flatter than the down – tin – facing side), this substrate can be cut to varying sizes and provided either as standard or in chemically/thermally toughened options.
Other ITO Glass Options
Our ITO coated glass options can be supplied:
- Fully dimensioned
- Profiled (chamfer edges) to meet customer requirements
Our use of state-of-the-art glass processing technology also enables us to provide substrates:
- Polished to specific flatness/optical requirements
- With cut-outs and/or holes as required
We can also provide ITO coated glass with further enhancements like, for example, printed borders/graphics or/and anti-glare finishes, as well as a range of OLED-grade smooth-surfaced ITO coated types of glass.
