ITO quartz transmittance graph

The light transmittance was compared with ITO electrode and Grid electrode (Au, Pt and Carbon) on a quartz glass as a reference. For ITO electrode, the light cannot be transmitted easily in ultraviolet range. The transmittance is about 10% at 250 nm of the wavelength. For wavelength above 350 nm, the transmittance is above 90%.

The thickness of the ITO membrane is 100±10 nm, and the surface resistivity is 15±1.5 Ω/sq.
Custom size is also available.

ITO borosilicate light transmission graph

The light transmittance was compared with ITO electrode and Grid electrode (Au, Pt and Carbon) on a quartz glass as a reference. For ITO electrode, the light cannot be transmitted easily in ultraviolet range. The transmittance is about 10% at 280 nm of the wavelength. For wavelength above 400 nm, the transmittance is above 80%.
