Labsphere’s Spectra-QT Quantum Tunable Irradiance/Radiance Calibration Source provides control of known levels of uniform monochromatic light over the spectral sensitivity range of silicon-based optical sensors for test and characterization imaging sensors for spectral responsivity and quantum efficiency, linearity, bad pixel and clusters of image sensors.

For the image sensor industry, accurate knowledge of its electro-optical quantum efficiency is essential to product performance. A well characterized sensor allows device integrators to specify and tailor the input optics of spectral filtering and apply performance enhancing corrections through the end product.
