Diamond Coatings Indium Tin Oxide Glass Options

Offering a diverse range of ITO indium tin oxide coated glass options, Diamond Coatings have established themselves as market-leading indium tin oxide glass suppliers. Here are some of the ITO glass options currently available to our customers.

ITO Indium Tin Oxide Coated Glass Substrates

The first choice customers have when looking for ITO coated glass is a choice of substrates. Options offered include:

BK7 Glass – Offering an average optical performance (uncoated) of 93 per cent (a performance that can be enhanced further by application of anti-reflective coatings), this comparatively expensive type of glass is manufactured in blocks before being cut to required thicknesses.

Widely used in high transmission display applications, it is then polished (both sides) to achieve specific required dimensions.

Borosilicate Glass – This glass type consists primarily of silica (70 per cent) and calcium, sodium, potassium and boric oxides (1, 8, 8 and 10 per cent respectively). Although this glass is appreciably more difficult to manufacture than traditional glass, its superior durability means it is highly economical in terms of production.

A so-called “crown glass” in optical terms, borosilicate glass offers:

• Low dispersion;
• Comparatively low refractive indices (between 1.51 and 1.54 across visible wavelengths);
• A very low thermal expansion coefficient (~3×10-6/°C @ 20 °C), and
• Chemical and heat properties of exceptional use within chemical laboratory, military and diverse other applications.

These properties combine to make this glass type the preferred choice for a diversity of TFT flat screens and critical display equipment.

Fused Quartz/Silica Glass – Containing primarily non-crystalline (amorphous) silica, these glass types are manufactured using different processes:

Fused Quartz is a usually transparent glass that is produced by melting high-purity naturally occuring quartz within gas/oxygen-fuelled (i.e. flame fused quartz) or electric (i.e. electrically fused quartz) furnaces at temperatures around 2,000º C.

Fused Silica is a usually translucent or opaque type of glass frequently also referred to as “higher standard fused quartz”. It is produced by melting high-purity silica feedstock within electric furnaces.

Soda Lime Glass & chemically or thermally toughened options there of form our most commonly used and most inexpensive substrate option.

Manufactured by drawing glass over baths of molten tin, which results in the upper side (facing the air) being flatter and smoother than the lower side (facing the tin), soda lime glass and the toughened options thereof can then be cut to diverse sizes.

Additional Indium Tin Oxide Glass Options

In addition, using ultra-modern processing technology we can provide indium tin oxide coated glass

• Fully dimensioned
• Profiled with chamfer edges to match customer requirements
• With radius, holes and/or cut-outs as required
• Polished to meet specific optical/flatness requirements
• With additional enhancements including, for instance, anti-glare finishes or/and printed graphics and borders

We can also offer a selection of smooth-faced OLED-grade types of ITO coated glass. Contact us today for more detailed information and/or to discuss the specific optical requirements of your application with one of our technical specialists.
