Create your own light by adjusting the 22 channels to your needs. You can simulate standard light sources, reconstruct the daylight distribution from dawn until dusk, create patches of a high saturated color chart, generate any standard illuminant, or reconstruct the spectral distribution of a measured light source. Moreover, by using the individual channels, you can even measure the spectral sensitivities of a camera.
The iQ-LED provides you with the closest match to standard D light sources in a broad range from 400 nm up to 820 nm. Aside from many other predefined light sources, you will also be able to generate your own custom spectra in combination with EX2. The dim function is realized with a pulse width modulation (PWM) of 32 kHz to work with short exposure times.
The 1000 step linear tuning of the intensity for each channel provides an accurate way to manipulate every part of the spectrum. The internal temperature stabilization enables a continuous frequency for a period of a few seconds to over a few hours. A quick and easy software-based self-calibration avoids any effects caused by burn-in or long-term degradation of the LEDs on predefined spectra, ensuring a long lifetime. Due to its extremely short response time, frequencies of the light settings can change up to 40 Hz. The technical characteristics of the iQ-LED are mainly designed for the higher requirements in the area of camera testing and camera calibration.
We provide the iQ-LED system combined with a micro-spectrometer and the control software as a stand-alone version. This iQ-LED bundle allows you to create your own light source adapted to your needs. If you need a higher intensity or want to create a larger spectral programmable light source, you can expand your system with several iQ-LED Add-ons.
The iQ-LED bundle uses a new mini spectrometer that has a better spectral resolution, higher sensitivity and a spectral range of 350 - 870 nm.
