CAL1 has a compact design consisting of one iQ-LED element in a 0.3 m integrating sphere that illuminates a 70 mm opening. Due to the non-reflective diffusor filter on the sphere opening, a uniformity of more than 98% is possible.
An integrated micro-spectrometer makes controlling CAL1 easy with the iQ-LED control software or, you can upgrade with the iQ-LED C++ API, and integrate it into your specific test procedures.
Furthermore, you only need one device for all light sources such as A, D50, D65, or any other standard light source or self-generated spectra. For spectral sensitivity measurements, the CAL1 allows individual activation for each of the 20 narrow band color channels. The main aspects of the CAL1 include camera calibration defective pixels, determination of luminance and color shading measurement, exposure adjustment, spectral sensitivity determination and much more.
As a result of the short response time of the iQ-LED, a full calibration can be performed in less than second, as long as the image processing and transfer in the camera is fast enough.
The CAL1 uses a new mini spectrometer that has a better spectral resolution, higher sensitivity and a spectral range of 350 - 870 nm.
