NIR Intensity Lens Solution

Click to Enlarge Thumbnails

Perform fast, accurate radiant intensity measurement of near-infrared (NIR) light sources and distributions with the NIR Intensity Lens, an integrated hardware and software solution. For emerging three-dimensional sensing applications at 850 or 940 nm, the NIR Intensity Lens solution ensures the performance and accuracy of devices and systems that use NIR sensing for facial and gesture recognition, eye tracking, and more. Measure NIR LEDs and lasers to assess Time-of-Flight (ToF) light-based proximity sensing and evaluate dot patterns produced by diffractive optical elements (DOE). The NIR Intensity Lens solution is an integrated camera/lens solution using a ProMetric® Imaging Radiometer with TrueTest™ Software and TT-NIRI™ Test Module.
