IR Filter Coating for heat shielding

The infrared radiation is responsible for the extremely high heat generation within closed devices. An infrared filter that protects against infrared radiation is therefore a thermal protection filter.

"The IR protection filter used by Interelectronix not only protects the touchscreen itself, but also the TFT screen behind it from overheating and premature failure." Christian Kühn, Glass Film Glass Technology Expert
The IR filter is applied as a foil or as an IR glass pane on the touch screens and reflects the incoming infrared radiation as far as possible.

The infrared filter thus reflects back the incoming radiation, which means that only a small proportion of the radiation enters the interior of the system and thus inhibits heat development.

NIR filters also act as EMC shielding. As a custom option, we offer NIR (Near Infrared Rejection) filters that are laminated to the back of the touchscreen.

By using an NIR filter, a large part of the infrared radiation is reflected while the visible light is allowed to pass through.
This means that only the infrared part of the light spectrum is blocked, which significantly reduces heat generation inside the device.

The aim of the use of sun protection films is to protect against infrared radiation and thus against internal heat generation, while at the same time showing all information in a clearly legible manner despite strong light irradiation on the display.

"Interelectronix uses only the highest quality and highly transparent infrared protective films and protective glasses, which guarantee long and maintenance-free use." Christian Kühn, Glass Film Glass Technology Expert
The high transparency and optical quality of the film used make it almost invisible and ensure optimal readability.
