I have a question regarding the safety profile of the IR LEDs in my current project. I have (3) infrared (~940nm) led "lamps" separated by several inches each which I am tracking effectively with a camera. But is it an eye-safe configuration? Tracking distance is ~1 to 12 feet and the illumination by the IR LEDs make them excellent beacons. All of the IR LED specs I have are below, pasted from purchase site (no other available). A synopsis: each IR LED drops ~1.7 volts, consumes 100ma forward current, power output = 150mw, and has a viewing angle of 90 degrees. I can also increase the diffusion of the LED with an abrasive material if that would help.
