Diamond Coatings R&D ITO Coated Glass Slides

Diamond Coatings Inc’s range of ITO glass slides includes a selection of high-quality ITO coated glass slides developed specifically for R&D laboratories.

Diamond Coatings Inc. offer an extensive range of ITO coated glass slides, including a comprehensive selection of high—quality ITO glass slides featuring a Si02 barrier layer, which were developed specifically for R&D laboratories. Here is why…

Available ITO Slide Grades and Sizes

Comparatively inexpensive to produce; available not only in standard but also chemically and thermally toughened options and easily cut into required sizes, soda lime glass is our most popular, most used glass type.

Vacuum depositing a transparent, highly conductive layer of indium tin oxide (or ITO) – In2O5Sn – onto soda lime slides furnishes the coated slides with the optoelectronic and electronic properties necessary to meet the requirements of many medical, scientific and R&D applications and projects.

We currently supply ITO coated slides in three different grades:

  • Standard 4.5 ohms/sq., 82% transmittance ITO coating
  • Standard 15 ohm/sq., 88% transmittance ITO coating
  • OLED grade 15ohm/sq., 86% transmittance ITO coating (the surface of which is smoother than the surfaces of the Standard options)

Currently available standard ITO slide sizes include:

  • 20 mm x 10 mm
  • 25 mm x 25 mm
  • 75 mm x 25 mm

We can also supply ITO coated glass slides cut to diverse other sizes up to a maximum of 400 mm x 500 mm.

The Problem with ITO Coatings on Soda Lime Glass

The problem with using soda lime glass for slides is that approximately 14wt% (14 g per 100 g) of soda lime glass consists of sodium oxide (Na2O) – and sodium ions tend to naturally leak (diffuse) out of the glass into the ITO layer.

Caused by annealing and potentially leading to both increased electrical resistivity and structural defects within the ITO layer, this diffusion can significantly affect not only the optoelectronic/electronic properties, overall performance and longevity of said layer, but also those of any devices grown upon it.

ITO Coated Glass Slides with Si02 Barrier

The diffusion of sodium ions between soda lime glass and ITO coatings can, however, be inhibited by a thin barrier layer of silicon oxide (Si02). Our ITO coated R&D slides therefore consist of 1.1 mm thick soda lime glass to which a 25 nm layer of Si02 has been applied prior to deposition of the ITO layer.

Nestled between the glass and the ITO coating, this sodium oxide barrier inhibits the diffusion of sodium ions and thereby increases both our ITO glass slides’ quality and their durability.

Projection Room Port Glass

Diamond Coatings supply a superior fire rated anti-reflective projection room port glass, perfect for the delivery of digitally projected media, in 2D and 3D.

Optical Coating Companies

We are an award-winning company and serve many differing industries, from entertainment, research and development, aerospace and automotive as well as military and defense. An example of products supplied include heated windows, capacitive switches and conductive PET films.

ITO Glass Substrate Options

ITO coated glass substrates are mainly used as conductive substrates in various applications, including solar cells and bio-sensors for instance. ITO coated films are applied to appropriate glass substrates which can be used to shield and reduce electromagnetic radio waves (EMI and RFI).

Anti-reflective Glass for Projectors

Diamond Coatings Anti-Reflective Glass is used in major theatres around the world. Our product provides more light from the projector and allows it to go through the port window glass and present a remarkably clear picture on the screen.
