Infrared LED choice for freetrack

[SEE]

Osram SFH485P are wide angle with flat head - thats how mine were listed and arrived. Probably the best you can get for HT clips and you can see wether they are working or not as they give off a faint orange glow similar to the TrackIR clip.

Worth noting that when I connected the new LEDs they appeared as enormous dots in Freetrack which quickly merged when I turned my head - very annoying. The problem was that the camera was badly out of focus and after manual adjustment it is now perfect with strong, small points.

You're right, See: There seems to be a naming convention with the P... Siemens delivers the 485 as roundhead and 487P as flat. I checked some more and found the P to be the most important: Osrams SFH485P emits in a 40° half-angle (Siemens' 487P in 65° half-angle and boths Osram's and Siemens' SFH 485 in 20° half-angle).

So whatever you choose: Be sure to get a wide angle with a "P" in its name.

Edit, Update: According to the datasheets, Osrams SFH485P emits in a 40° half-angle, not in a 160° angle as originally said.

I just sanded the round tips of the LEDs down with fine sanpaper. Worked really well for me
