The iQ-Chart Box is a light source that has a compact design with built-in iQ-LED V2 for illuminating size A460 and A280 reflective test charts. Each light is aligned and fixed to ensure test charts are always homogeneously illuminated.
iQ-LED V2 technology is a light source that is capable of generating custom spectra to replicate various light sources in a test lab environment. The iQ-Chart Box has eight iQ-LED V2 elements built into it that each use 20 LED-channels to recreate almost any light spectrum for your camera testing.
The iQ-Chart Box is designed with small test labs in mind. Now, instead of having a full chart mount and two or more free standing lights to illuminate the test chart, you can have the same illumination features all inside the box.
The iQ-Chart Box uses a mini-spectrometer with a spectral range of 350 – 860 nm to ensure better spectral resolution and higher sensitivity of the iQ-LED lights.
iQ-LED control software is provided with the iQ-Chart Box. An iQ-LED API is also available as an option for integration into your custom design.
