Santa Paula, CA – Abrisa Technologies can provide both Indium Tin Oxide (ITO) and Index-Matched Indium Tin Oxide (IMITO) thin film optical coatings for a wide variety of optics applications. The durable coatings provide for an electrically conductive glass surface that offers high optical transparency with transmittance levels that can be in excess of 99%. Common wavelengths for the coatings are 400 to 700 nm (visible) and 1500 to 1650 nm (near IR). A variety of sheet resistances such as 5 ohms per square for shielding applications and higher values for heater applications can be provided depending upon the particular application requirement. Glare reducing broadband anti-reflective coatings can also be applied to the glass substrate along with the ITO/IMITO coating.


ITO/IMITO coatings are commonly used to shield electromagnetic interference (EMI) while transmitting a high level of visible light, as heater windows for outdoor use, and in electronic devices such as LCDs and switches. The coatings can be applied to a wide variety of commercial glass such as soda lime float glass, borosilicate and aluminosilicate glass as well as other technical substrates such as ceramic, and fused silica.


Typical applications for ITO/IMITO coated glass include:

  • Liquid crystal, flat panel, plasma, and touch panel displays
  • Heated and anti-static windows
  • Transparent EMF, EMI EMC, RFI, and HF shielded glass
  • Instrumentation
  • Electronic displays
  • GPS systems
  • Outdoor displays
  • Heater panels

ITO and IMITO coatings from Abrisa Technologies are resistant to flaking, peeling, cracking, delaminating, and crazing. The coatings can be applied to substrate sizes as small as 0.25″ and up to a substrate size as large as 27″ in diameter. The minimum substrate thickness that Abrisa Technologies can provide ITO coatings for is 7 µm while the maximum substrate thickness that can be coated is up to 4″.


Custom fabrication of ITO/IMITO coated glass can include the addition of Bus Bars, custom edge treatments, opposed drilling of holes, custom cutting, chemical strengthening, screen printing, wire bonding, and more, for a fully integrated optics solution.


All ITO/IMITO coatings are applied via an ion assisted physical deposition process which provides an extremely uniform film while virtually eliminating macro particle content.

Indium Tin Oxide (ITO) Coatings
Provide High Transmittance
Solutions for Optics Applications

Photonics West 2011 – Torrance, CA – ZC&R Coatings for Optics, a division of Abrisa Technologies, provides Indium Tin Oxide (ITO) and Index-Matched Indium Tin Oxide (IMITO) transparent, high transmittance conductive coatings which are extremely useful in EMI shielded windows for sensors and displays, heated outdoor camera windows, liquid crystal based polarization devices, and photovoltaic cells. The high transmittance IMITO solutions can be designed with sheet resistances below 5 ohms per square.


These IMITO solutions inhibit the effects of EMI (Electro-Magnetic Interface), RFI (Radio Frequency Interface), and ESD (Electro-Static Discharge). By using an ITO coating solution from ZC&R Coatings for Optics, EMI, RFI, and ESD are minimized and may be virtually eliminated; improving reception and overall performance of electronic devices. Instrument operators and communications devices will have clearer signals and improved communication channels due to the coating’s effectiveness.


The ITO and IMITO coatings can be applied to a wide variety of technical and commercial glass substrates and may be applied in conjunction with other ZC&R coatings for a highly custom, application-specific solution.


The optically transparent and durable ITO and IMITO coatings are most often used where low resistance and high transmission are required. ZC&R’s high transmittance coatings are resistant to flaking, peeling, cracking, delaminating, and crazing. Humidity, abrasion, adhesion, and salt-fog should be considered when selecting a coating prior to application for best results.


Integrated durable Bus Bars can be provided with tri-metal or precision printed high temperature silver epoxy for electrical contact.
