Diamond Coatings Ltd

UK based company specialising in ITO indium tin oxide coatings, designed for displays, computer touch screens and control panels.

DIAMOND operate state-of-the-art magnetron sputtering plant, equipped with clean rooms, from modern factory premises located near Birmingham, England. The plants are capable of depositing uniformly onto flat or shaped glass or plastic substrates up to 1000mmx1000mm in size. Other production facilities, which complemented our vacuum coating capability include material processing, patterning indium tin oxide and silk screen printing. These facilities are operated by a highly trained staff with over 50 years experience of vacuum coating technology.

ITO - Coatings (Indium Tin Oxide)

DIAMOND's principle products include:

Diamond Coating Limited is a privately owned company and is a leader in the development and production of vacuum coatings including indium tin oxide (ITO), for niche markets in the electronics and electrical industries.

We aim to give a design guide for choosing and using ITO coatings. Typical ITO antistatic and EMC coatings are outlined and their performance described.

Anti Reflective Coatings

Diamond Coatings Limited  supply blue chip companies as far afield as the USA and the Far East with the majority of work going to Europe Diamond Coatings Ltd also has a satellite factory in North Carolina in the USA supplying high quality display units within America.

Glass any make of glass from 0.1mm coverslips to 20mm thick screen protectors, we can also offer anti-glare coatings.

Plastic most makes of plastic including Ploycarbonate, Acrylic and CR 39. Sheet thickness can vary from 0.75mm polyester film to 25mm plastic sheet.

Special Items are ITO coated such as hand held scanners, moulded screens and printed overlays.

Anti Reflective Coatings available on a number of substrates

Machining Substrates can be produced and machined into all kinds of shapes and sizes, rebates to machined steps, chamfered corners to machined holes.

DIAMOX Indium tin oxide (ITO) coatings

Busbar Following the substrate and ITO coating to finish your product if required we can offer either silver or copper adhesive busbar or for more critical windows a screen of printed silver loaded busbar is available.

We are able to coat the largest coating sizes in Europe

ITO 1000mm x 1000mm
ITO matched 400mm x 1000mm
AR coating 400mm x 1000mm


DIAMOX Indium tin oxide (ITO) coatings are produced by low temperature vacuum deposition. The ITO is a highly conductive transparent coating and is available deposited on to glass or plastic substrates including polycarbonate, acrylic and polyester. A flexible system for handling the substrate enables both flat and shaped, as well as a range of injected moulded parts, to be coated.

DIAMOX coatings are available with a sheet resistance from 10 to 1500ohms/square in sheet sizes up to 1000mmx1000mm. Diamond can supply fully machined glass and plastic parts and also provides an ITO coating service for free issue parts.

The DIAMOX coating can be etched to produce fine conductor paths.


The typical peak light transmigration, in the wavelength range 525 to 600nm, for a 20ohm/sq coating on glass is 87% and on polycarbonate 81%.

Durability There is no evidence of optical degradation or a reduction in coating adhesion or sheet resistance when DIAMOX coatings have been subjected to Thermal Cycling, Salt Spray and Humidity Cycling (To MIL STD 48497).

EMI/RFI Shielding Effectiveness. Using test methods consistent with MIL-STD-215, DIAMOX ITO offers a shielding effectiveness up to 58dB at 1MH and 26dB at 1GH.
