NIR Intensity Lens

Fast, accurate radiant intensity measurement solution for evaluation of near-infrared light sources and distributions


Measuring Near-Infrared (NIR) Light Sources for Effective 3D Facial Recognition

Three-dimensional sensing technology is the foundation of multiple new applications, such as:

  • Facial and gesture recognition
  • Eye tracking and iris detection
  • Automotive LiDAR for autonomous vehicle sensing
  • Multimodal sensing for vehicle gesture and motion control
  • Other near-infrared 3D sensing applications

Measurement techniques for NIR LEDs and lasers ensure the performance of Time-of-Flight (ToF) light-based proximity sensing and 3D sensing using dot patterns produced by diffractive optical elements (DOE). To ensure performance and accuracy of devices and systems that use NIR sensing, an effective test and measurement solution is needed.

Near-Infrared Intensity Lens Solution

The Radiant Vision Systems Near-Infrared (NIR) Intensity Lens system is an integrated camera/lens solution that measures the angular distribution and radiant intensity of 940 nm near-infrared (NIR or near-IR) emitters. The NIR Intensity Lens system utilizes Fourier optics to capture a full cone of data in a single measurement to ±70 degrees, giving you extremely fast, accurate results ideal for in-line quality control.

Manufacturers of 3D sensing technology can apply the NIR Intensity Lens solution for angular measurement of NIR LEDs, lasers, and structured light patterns produced by Diffractive Optical Elements (DOE). The lens mounts directly to a Radiant Vision Systems ProMetric® Y16 Imaging Radiometer, and features ProMetric or TrueTest™ Software for intuitive system setup and customizable automated measurement sequences. Additional tests specific to NIR emission measurement are available.
