Hi, one of the Ir-LEDs seem to have broken on my Trackir 3.
The trackir still works fine, but I want to replace it anyhow.
(yes I'm a skilled solder
So the question is, what kind of Ir-LED should I use?

The main thing I think is the emmitted light (mW/sr)and perhaps the "beem angel"? How powerfull LEDs is used in the original ones?


I have not found any other voltage than 1.2-1.5, so that should not be a problem?

Anyone that help me with this?

The LEDs emit at 880nm and are standard off the shelf IR LEDs; we run them all the time when the unit is turned on. There are 4 of them and they each have a total radiant output of about 23mw/sr, which is 23miliwats per ster radian. Total output power is NOT 4 X 23 mw/sr as the LEDS do not overlap exactly
