iQ-Multispectral

The iQ-Multispectral is a multispectral illumination device based on iQ-LED technology that enhances digitalization and the preservation of documents, texts, and images.

Multispectral imaging is used to visualize certain inscriptions on objects that are not visible using standard photography. An example is the hidden inscriptions on the security printing of a euro banknote. Under the right light, different inscriptions on the banknote can be seen.

The iQ-Multispectral device uses a narrowband light-source method. As previously stated, this device is based on iQ-LED technology and features 19 visible-range channels and 11 additional VIS-IR channels. It also contains one UV LED.

The iQ-Multispectral therefore covers the spectral range between 380 nm and 1050 nm. In addition, the UV LEDs (at 365 nm) use a bandpass filter to block visible light.

The device's setup is very similar to that of a typical reprographic stand. You can combine the solution with any holder or book cradle that supports a standard light source. Our solution builds on the Kaiser reprographic system (you can purchase the lights separately, without a stand, and use a custom stand or setup) and is designed for original paper sizes up to A2. Please be aware that the light sources and the stand are sold separately.

The device is delivered with the iQ-LED control software for complete control over the illumination. With this software, you can generate specific spectral distributions of light (e.g., daylight or tungsten) for standard reprographic applications, or activate individual channels for multispectral applications and store them for future use. You can also create fully automated sequences with selectable time intervals.

We offer an optional advanced programming interface (iQ-LED API) for integrating the system into custom software.

As a basic setup, you can also choose to have the iQ-Multispectral delivered without a spectrometer* and instead with a device preconfigured with illuminants. These illuminants must be individually requested (up to 40) and programmed into your device before delivery.

This option significantly reduces the product's total cost and is an excellent choice for new or smaller test labs looking to upgrade their image quality testing.

Please contact our sales department to get started with a basic product.

*A spectrometer can be purchased at a later date if desired.

Multispectral imaging is used to visualize certain inscriptions on objects that are not visible using standard photography. An example is the hidden inscriptions on the security printing of a euro banknote. Under the right light, different inscriptions on the banknote can be seen. To enhance the digital preservation of documents, images, and old texts, it's crucial to ensure that every layer is preserved when converting them to digital formats; otherwise, essential artifacts, colors, or inscriptions may be lost, and the overall meaning may be misinterpreted. The iQ-Multispectral device uses visible, infrared (IR), and ultraviolet (UV) light to enhance target illumination and capture critical details.
