The iQ-Chart Box makes it possible to illuminate reflective test charts quickly and homogeneously. It is the compact solution for providing optimal conditions for testing image quality in cameras and cell phones. Whether measuring resolution or color reproduction, you can use all of the reflective test charts that we offer in the A460size. Chart changing is carried out quickly and easily by means of a movable carriage. The lighting systems in the iQ-Chart Box are precisely aligned and fixed; the test charts are always optimally and homogeneously illuminated.
Another highlight is the spectrally programmable iQ-LED light source. With the intuitive software provided, you can quickly determine the kind of beam and intensity used and then be able to check the image quality in different lighting situations. Also, there are four dimmable fluorescent lamps available.
If you want to illuminate test charts for measuring your camera or mobile phone’s image quality in a more time and space-saving way, then the iQ-Chart Box is the right solution!
The iQ-Chart Box uses a new mini spectrometer that has a better spectral resolution, higher sensitivity and a spectral range of 350 - 870 nm.
The entire illumination consists of 8 durable iQ-LED elements (640 LEDs) and four fluorescent lights. It is possible to dim the brightness between 500 lux and 25 lux at the chart level. With the additional folding ND filters, it is even possible to reach an illumination of just 1.5 lux.
The adaptation of the spectral curve for the desired illumination takes place in the visible range (400 - 820 nm) with the spectral programmable iQ-LED light source. Through the software, all of the iQ-LED technology features can also be used: standard illuminants, test sequences, individual spectral curves and more. Calibration is performed using the supplied spectrometer.
An API is also available for automated control.
