LE7 with iQ-LED technology
The iQ-LED is the latest development of Image Engineering. It is a multi channel 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. Available in two intensities (2x and 4x).
The LE7 with two iQ-LEDs is the latest development project of Image Engineering.
It is a multi channel LED light source that gives you the possibility to generate the spectral characteristics of nearly every needed light source in just one device. With its 22 different software controlled LED channels it is possible to generate the spectrum of standard light sources such as D50, D55, D65, A, B, C etc. with a very high accuracy. Next to that, you can generate your own spectrum, for example to sample the spectrum you have measured on-site. 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 iQ-LED is the first Image Engineering product that uses this new kind of light source. The integrated spectral radiometer, combined with the iQ-LED Control-Software, enables the user not only to select from different predefined light sources, it also allows him to create his own spectral arrangement and saves these to recall it anytime and for any kind of testing. Because of the usage of different LED types over a broad range of the spectrum it is possible to use narrowband illuminating in different spectral areas and creating any kind of color. Changing between different light settings is possible without any delays and can be arranged as a test procedure, defined per software by your own will.The basic design of the LE7 is close to our previously LE6, so all testcharts can still be used as usual.
