Re: Target illumination LEDs - What color? How bright?

I built a demo illuminator that used 3 Cree xrc green less running at 300 ma . If they were more than 10 cm outside the range of the camera the reflection fell dramatically. When using the ledil optics I could not get a wide enough beam angle. It was flooding the camera.

We have 9 xrc less now on tristars that can illuminate across the entire field, but the team is using the largest angel eye instead.
