NIR Intensity Lens

Fast, accurate radiant intensity measurement solution for evaluation of near-infrared light sources and distributions. 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 850 or 940 nm near-infrared (NIR or near-IR) emitters. The NIR Intensity Lens system utilizes Fourier optics to capture a full distribution of angular NIR light in a single measurement up to ±70 degrees, giving you extremely fast, accurate results ideal for in-line quality control. Manufacturers of three-dimensional sensing technology can apply the NIR Intensity Lens solution for angular measurement of NIR LEDs, lasers, and patterns produced by diffracted laser light.

The lens mounts directly to a Radiant Vision Systems ProMetric® 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 through the TT-NIRI™ Software module.
