The LE7 with LED technology is a multichannel LED light source that provides the possibility to generate the spectral characteristics of nearly every required light source in just one device.
With its 22 different software controlled LED channels it is possible to generate a spectral match of standard light sources such as D50, D55, D65, A, B, C etc. with very high accuracy. You can generate your own spectrum, for example to match a given light source. The technical characteristics of the iQ-LED are particularly designed for the high requirements in the field of camera testing and camera calibration.
The LE7 with 2x iQ-LEDs is the first Image Engineering product that uses this new kind of tunable light source. The integrated spectral radiometer combined with the iQ-LED control software, enables the user to select from different predefined spectra, and also allows to create and save custom spectral distributions and which may be reused anytime. Using different LEDs over a broad range of the spectrum enables narrowband illumination in different spectral areas to basically create any kind of color. Changing between different light settings is possible without any delays and can be defined individually by using the control software. The basic design of the LE7 is close to our previous LE6, so all the test charts can still be used.
