For SFH485P, it means a standard of LED that many companies can produce it, or a certain company's products?
So far as i know, there are SFH485P-1 -2 ... What about them?
With best regards

Hello Silenthunter
You can use any variant of SFH485P, since we don't need to fine-tune the IR beam (if i remember, the -1 and -2 are only for guaranteed IR beam strength).
So , as long as its a SFH485P, its ok.
About the companies, to my knowledge, the SFH485P has manufacturers :
* OSRAM
* SIEMENS
Btw, with a bit of tweaking , about every 5mm IR led is fine for FreeTrack (some need sanding to acheive beam angle, other need IR modded webcam to get the best of , but every IR led is able to work).
