Measure Intensity of Near-IR Lasers & LEDs Used for Sensing

27 May 2020

Easily measure the intensity of near-infrared light sources used for sensing applications, from facial and gesture recognition to eye tracking and LiDAR. 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 near-infrared emitters. The NIR Intensity Lens system utilizes Fourier optics to capture a full angular distribution of light 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 measurement of NIR LEDs, lasers (VCSELs), and structured light patterns of dots produced by Diffractive Optical Elements (DOE). The solution is equipped with measurement software featuring a unique test suite for measuring the qualities of near-IR LED and laser sources. Evaluate flux and power, dot patterns and dot positions, and flood source uniformity and hot spots, as direct measurements and given in angular coordinates. The lens system can be integrated into production lines using factory communications for fully automated testing, as well as used in the lab for light source characterization.

Key features of the NIR Intensity Lens solution:

· Accurate and reliable measurement of radiant intensity out to ±70° angle.

· High angular resolution (approximately 0.05 degrees per CCD pixel).

· Efficient operation, capturing data for all angles simultaneously. Faster than goniometric systems for efficiently qualifying angular data.

· Compact form factor through integrated camera/lens design.

· Combination of low cost, high performance, and flexibility.

· Easy-to-use measurement control and analysis software for design or production inspection.
