Spectra-QT Quantum Tunable Irradiance/Radiance Calibration Source
Ideal for testing spectral response of silicon based optical sensors.
For the image sensor industry, accurate knowledge of a sensor’s electro-optical quantum efficiency is essential to product performance. A well characterized sensor allows device integrators to specify and tailor the input optics and spectral filtering and apply performance enhancing corrections through the end product.

Always Know the Light Levels on your Sensors
The integrated sphere detector is calibrated to monitor irradiance or radiance at the constituent wavelengths. Also with selectable apertures for defined F/#s you’ll always know the light levels on your sensors for a given field of view.

Complete Control
The QT-1000 user interface allows for complete control of light sources, bandwidth, gratings, ND Filter wheel, test wavelengths, and irradiance and radiance ports. Plus the LS-QUEST LabVIEW API gives you complete control for synchronizing testing with your sensor response.
