Decorative near-infrared transmission film, which transmits near-infrared rays and blocks visible light, is attracting attention in various fields for its characteristics.
Decorative near-infrared transmission film is a film that blocks visible light while allowing near-infrared light to transmit through, by using special materials and a special structure. Although the film appears white to the human eye, it is transparent to the near-infrared sensor, making it possible to improve the appearance of the product without compromising the performance of the sensors.
Decorative near-infrared transmission film can be added in various colors and patterns (such as wood-grain patterns). By combining it with color films that transmit infrared rays, it is also possible to make the colors more vivid.
As decorative near-infrared transmission film can be manufactured using roll-to-roll*, it is possible to produce large-area sheets. Therefore, it can be applied to large areas such as walls, advertising signs, and window glass. For example, by attaching a decorative near-infrared transmission film to one wall of a room, the room can be hidden from the outside while near-infrared cameras can see inside the room.
* Roll-to-roll: A technology to adding functions while rolling out and winding up a roll of film.
Decorative near-infrared transmission films are utilized in the following fields, taking advantage of their characteristics.
Security cameras | Ideal for locations where you do not want the camera to stand out. |
---|---|
Human flow sensor | The sensor can be installed in busy areas without making it stand out. |
Infrared sensor cover | Protects the sensor without compromising the designability of the robot. |
---|
Wall advertising | Clear images can be projected even in bright locations.
It is possible to embed two-dimensional code that can be read with near-infrared rays. |
