LE7 with iQ-LED and different illuminance

February 04, 2013

The iQ-LED is the latest development project of Image Engineering. It is a multi channel LED light source that gives 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, the user can generate his own spectrum, for example to sample the spectrum 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 the user own will.

The basic design of the LE7 is close to Image Engineering previously LE6, so all testcharts can still be used as usual. The launch of the LE7 with iQ-LED is planned for mid-summer 2013. A prototype will be introduced at Electronic Imaging Conference in Burlingame, California.
