ZEISS optical gratings and spectrometers allow for the optical inspection of LEDs for quality assurance and control as well as testing and binning during production. Binning systems in particular ensure tight consistency in color and the electrical characteristics of LED batches, which guarantees high product quality. ZEISS CGS-CCD spectrometers (190 - 1015 nm) are ideal for LED quality control and for binning systems measuring luminosity and chromaticity. The CGS spectrometer features a high sensitivity BT-CCD with minimal integration times (30 μs), global electronic shutter, excellent thermal stability (< 0.02 nm/K) and low stray light (< 0.01 % uncorrected). The optomechanical design also provides long-term stable calibration and high measurement repeatability. Plane gratings  in the UV-VIS to NIR spectral range with line densities  from 30 l/mm to 3600 l/mm enable customized spectrometer solutions for our customers with the lowest resolution and low stray light, enhancing the optical performance of spectrometers.
