Part of Diamond Coatings Ltd, ITO Coatings UK provide a diversity of indium tin oxide coated glass slides and coverslips on numerous substrate options. Here are some of these options.
Substrate Options for Indium Tin Oxide Coated Glass
We can currently offer to apply our Ito coatings (Custom Diamox and Index Matched Diamox+), as well as, of course, our Diamond AR (anti-reflective) coating to glass substrates including:
BK7 – Boasting a standard optical performance (average, uncoated) of 93% (a performance that can be improved further by application of an anti-reflective coating), BK7 glass is widely used widely for high transmission display applications.
Produced in blocks, this comparatively expensive type of glass is cut to required thicknesses and polished to achieve specific required dimensions.
Fused Silica & Quartz – These two types of glass primarily contain amorphous (i.e. non-crystalline) and different processes are used in their production:
- Fused silica or, as it is frequently also called “higher or high standard fused quartz”, is produced by melting high-purity silica sand feedstock within an electric furnace. The material resulting from this process is usually translucent or opaque.
- Usually transparent, fused quartz glass is produced by high-purity naturally occuring quartz being melted within an oxygen/gas fuelled or electric or furnace at temperatures of approximately 2000º C.
Borosilicate Glass – This low-soda glass primarily contains:
- 1 per cent Calcium Oxide
- 8 per cent Sodium Oxide
- 8 per cent Potassium Oxide and
- 10 per cent Boric Oxide
- 70 per cent Silica
Although producing Borosilicate glass is somewhat more difficult than producing traditional glass, this type of glass boasts superior durability, which makes production highly economical. An optical “crown glass”, borosilicate glass offers:
- Low Dispersion
- Comparatively low (1.51 – 1.54 across visible wavelength ranges) refractive indices
- Chemical & heat properties of exceptional use for chemical laboratory, military and numerous other applications
Combined with an equally low (~3×10-6/°C at 20 °C) thermal expansion coefficient, these properties make borosilicate a very popular choice for TFT flat screens and diverse critical display equipment.
Soda Lime Glass – The most commonly used and least expensive (due to low processing costs) substrate option, soda lime glass is created by drawing glass over vats containing molten tin, a process that typically results in the upper side of the glass being both flatter and smoother than its lower side. Available as standard or in thermally and/or chemically toughened versions, this glass is cut to diverse required sizes.
Additional Options
In addition to offering these substrate options, we can also supply ITO glass:
- Fully dimensioned
- Polished to comply with specific flatness and/or optical requirements
- Profiled (radius, chamfer)
- With required holes/cut-outs
Further enhancements like, for instance, anti-glare/anti-reflective finishes and/or printed graphics and borders, can also be provided, as can a range of smooth glass types suitable for OLED grade applications.
