iQ-Flatlight

One of the most important aspects of image quality testing is ensuring that your reflective test chart or test scene is properly illuminated. Many labs have only standard light sources, which cannot create a wide range of lighting conditions. The iQ-Flatlight addresses this issue with iQ-LED technology.

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. As with our other iQ-LED products, the iQ-Flatlight uses 20 LED channels to emulate almost any light spectrum for your camera testing. Each light contains ten iQ-LED V2 elements, achieving a maximum intensity of 2000 lux per pair on the chart plane and a spectral range of 380-820 nm.

With the introduction of iQ-LED V2, it is now possible to control the lights' functionality without a PC. You can store up to 44 distinct illuminants and one sequence on the device (controlled via microswitches on the device).

The iQ-Flatlight uses a mini-spectrometer with a spectral range of 350–860 nm to achieve higher spectral resolution and sensitivity. The spectrometer is also able to calibrate the lights.

It is also the perfect complement for VCX testing. All of the light sources outlined in the VCX white paper can be recreated with the iQ-LED, which allows for more efficient VCX mobile phone testing.

The iQ-Flatlight is always sold as a pair of two and includes iQ-LED control software (which has predefined standard illuminants) and a height-adjustable rolling cart for each light. We also offer an iQ-LED API as a separate option.

Each iQ-Flatlight is available with the standard 10 iQ-LED modules.

The iQ-Flatlight uses iQ-LED technology to generate custom spectra for advanced and flexible camera testing.

The iQ-Flatlights are ideal for uniformly illuminating reflective test targets/charts.

The iQ-Flatlight provides a uniformity of >90% on a large test chart (sample setup).

The iQ-Flatlight is the ideal light source for testing mobile phone and webcam systems according the VCX standard.

We can provide versions of the iQ-Flatlight with additional wavelengths, e.g., extending the visible spectrum into the infrared (on request).

iQ-Flatlight can be controlled using the iQ-LED control software, and we also offer an iQ-LED API.

The VCX-PhoneCam standard outlines test procedures and metrics for evaluating image quality in mobile phone camera systems. The VCX-Forum is a non-profit organization that provides objective camera test measurements and metrics to determine a final score for each mobile phone camera system. The purpose is to provide consumers with an objective evaluation when they are searching for a new phone. The VCX test includes metrics such as resolution, texture loss, color accuracy, visual noise, dynamic range, and distortion, among others. Each metric must be tested under defined lighting conditions, e.g., bright and low-light. Using iQ-LED technology, the iQ-Flatlight can generate each lighting condition outlined in the standard. This solution provides an all-in-one light source for testing cameras across various lighting conditions.

We are happy to discuss our customers' needs and can also provide versions of the iQ-Flatlight with additional wavelengths, e.g., extending the visible spectrum into the infrared. Please get in touch if you are interested in customization options.
