Hi all,

I am in need of Transparent ITO Film in the wavelength range of 400nm to 4000nm. Kindly help where i can get this part?

Indium Tin Oxide.
Looks fascinating. Clear plastic sheet coated with transparent conductive substance.

Adafruit website sells small frames. $5.95 & 9.95.
Demo video has led's glued to the surface, lit up without visible wires.

Hi,

Thanks for the reply. But I am in need of ITO Film or glass wavelength range of 400nm to 4000nm.

Clearer specification required. Plastic films have IR absorbance, e.g. at 3.4 um, may be acceptable though. Thin IR glass or fused silicia should work. What's the application?

Hi,

I am using it for EMI Shielding.

I am using it for EMI Shielding.

O.k., but which requirements drive the optical specification?

Hi,

Sensor which i am using have that wavelength.

Sounds like you didn't yet fix an exact specification, e.g. of required transmittance. Respectively don't expect clear answers.

For optical sensors, we often choose window materials with sufficient rather than perfect transmittance if they offer better mechanical properties. But your application may require a flat transmission spectrum for some reason.

Hi,

I am placing this Transparent Film on the sensor for EMI Shielding. My sensor wavelength is 400nm to 4000nm. My required transmittance is 400nm to 4000nm.

Presume that no polymer film has flat transmittance over 400 to 4000 nm spectral range.

PTFE film might work.

Hi Fvm,

Thanks for the reply. I need transparent film. can you please the data for PTFE which have the wavelength of 400nm to 4000nm. Kindly share.

Hi,

Kindly refer the image attached. I think in PTFE film, there is no optical transparency. In this case, what will be the solution?
