I've also used this the other way around, using a fiber optic cable to route light to the phototransistor itself. Do this with more than one light sensor, and you can have much better spatial resolution (the ends of two fiber optic cables can be right next to each other; not so the light sensors themselves). -- Brian Davis

(...) Hi Brian, What kind of application needed this precision? Line follower? Did you need to shield the fiber to avoid stray coupling of light to the phototransistor? Philo (18 years ago, 18-Dec-06, to lugnet.robotics.nxt)

Hello Geoffrey, (...) First, don't worry about heat - such leds are really cool (thermically wise) devices! This one dissipates only about 20 mW... Your fiber optic cable idea is interesting... and it works well! I used the fiber optic cable (...) (18 years ago, 17-Dec-06, to lugnet.robotics.nxt)
