850nm IR LED ring light suggestions
Posted: Sun Feb 15, 2015 4:06 am
Hello all,
For a V120 do you have any suggestions for off-the-shelf 850nm IR LED ring lights ?
Preferably the power electronics would be separable from the ring itself (so as to keep weight down on the arm of a facial motion capture helmet). The ring would be minimal in mass also.
Power and focus would be enough illuminate a face, such that with the V120 850nm band pass filter in place and an indoors lighting situation (no heavy IR from the sun, or otherwise) the IR LEDs would be the bulk of the illumination and other 'white' light wouldn't have much of a relative IR component. (Hope that makes sense
)
Also, I understand that NaturalPoint develops it's own ring lights for the Optitrack range so if I had to roll my own for my V120, perhaps do you have any suggestions for the LED part? and also how best to go about power stage design?
(V120 is 'without case' option, and with 22mm outside diameter 4.5 mm M12 lens)
Any help greatly appreciated
