I'm looking for a cheap and cheerful infrared laser pen for a university experiment; I basically want to point it at an ir receiver diode (the same type you get on most ir controlled rc toys) 60 meters away and send pulses to it for the sake of communication.
As this is what I want to do I don't need anything capable of burning etc, just an eye safe pen that i can play around with without worrying too much about the risk of being blinded, however all I seem to be able to find at the moment are high powered burning lasers.
Can someone possibly point me to something closer to what I've described?
Many thanks in advance.
