Diamox+ Index Matched (Indium Tin Oxide) ITO


Boasting all DIAMOX characteristics, DIAMOX+ provides for index matched ITO Oxide coatings.

In comparison to standard ITO coatings, DIAMOX+ index matched ITO (Indium Tin Oxide) coatings offer significantly improved rates of light transmission.

DIAMOX+ ITO Oxide Coatings

DIAMOX+ coatings are multi-layer coatings of metal oxides and quartz. The quartz layer’s thickness is carefully controlled in order to enhance the transmission and suppress unwanted reflection. DIAMOX+ can be deposited onto acrylic, polycarbonate and glass substrates. Currently available sheet sizes range up to a maximum of 1000 mm x 1000 mm.

Product Information

Typical transmission curves (spectral) for 15 ohms/sq Standard Diamox and Diamox+ Index Matched ITO coatings are provided in the data sheet.

Typical peak light transmissions for 20 ohms/sq polycarbonate and glass substrates coated on one side are 84% and 92% (525 to 600 nm wavelength range).


Subjection (MIL STD 48497) of Diamox ITO coatings to humidity cycling; salt spray and thermal cycling have provided no evidence of sheet resistance reduction; reduction of adhesion or optical degradation within the ITO coating.

RFI/EMI Shielding Effectiveness

At 1MH and 1GH and using MIL-STD-215 test methods, Diamox ITO coatings offer shielding effectiveness of up to 58db and 26db respectively.

Transmission Graphs

We produce an extensive range of ITO oxide, Multi-Layer Anti-Reflection and Index Matched coatings. Many of these coatings are designed to match specific optical requirements for customers. We can also provide transmission and reflection graphs for our full range of optical coatings.
