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 angular distribution of NIR light in a single measurement to ±70 degrees, giving you extremely fast, accurate results ideal for in-line quality control.

Key Features

• Highly accurate NIR emission measurement over angle
• Analysis of structured light patterns oroduced by lasers (dots, grids, and arrays)
• High-speed operation, capturing data for all angles simultaneously
• Easy-to-use measurement control and analysis software
• Optional TT-NIRI™ Software with a suite of analyses for NIR source measurement

Benefits

• Accurate and reliable measurement of angular emissions up to ±70° at once
• Faster than goniometric systems; more accurate than measuring distributions on a wall
• High angular resolution (to 0.05 degrees per sensor pixel)
• Compact form factor
• Combination of low cost, high performance, and flexibility

Applications

• Angular measurement of near-infrared (NIR) light sources used in facial recognition, eye tracking, monitoring, and 3D sensing applications
• Turnkey evaluation of 850 or 940 nanometer (nm) light sources for accurate radiant intensity output at all angles
• In-line measurement for both R&D and quality control during production, ensuring safety and performance
