Diamox+ Index Matched (Indium Tin Oxide) ITO


DIAMOX+ boasts all the characteristics of DIAMOX but provides for an index matched ITO oxide coating.

The DIAMOX+ index matched Indium Tin Oxide (ITO) coating offers significantly improved light transmission compared with standard ITO oxide coatings.

The DIAMOX+ coating is a multi-layer coating of quartz and metal oxides. The thickness of the quartz is carefully controlled to suppress unwanted reflection and enhance the transmission. DIAMOX+ is available deposited onto glass, polycarbonate and acrylic substrates. Sheet sizes up to 1000mmx1000mm are currently available.

Product Information

Spectral Typical transmission curves for DIAMOX Standard and DIAMOX+ indexed matched ITO oxide (15 ohms/sq) are in the data sheet.

Light Transmission on Glass and Polycarbonate Substrates (20 ohms/sq)

Glass Polycarbonate
One Side Coated 92% 84%


The above are typical peak transmissions in the wavelength range 525 to 600nm.


There is no evidence of optical degradation or a reduction in coating adhesion or sheet resistance when DIAMOX ITO oxide 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.
