ITO Fused Quartz Windows & Plates

UQG Optics ITO coated indium tin oxide is vacuum deposited on one side on the Fused Quartz substrate which is a highly conductive transparent coating. When the ITO coating has been exposed to thermal cycling and salt spray it has shown no reduction in optical performance or damage to the ITO coating. The transmission will peak to 87% @ 525-600nm wave range on 20 ohm/sq coating. For higher transmission the ITO can be index matched with multilayer AR coatings. The Fused Quartz or Fused Silica windows can be supplied ITO coated up to 1 metre square in a range of sheet resistance from 2.50 to 1500 ohm/sq. Used in science and industry for many applications.

UQG Optics stock range is limited and additional sizes will be stocked shortly.
