  • Looking for alternatives for Optotrak markers !

    Hello all,

    Since the markers for the Optotrak 3020 system cost $27 each (exc. VAT)
    nowadays, and I'm in the need of about 50 of them, I'm looking forward to
    any information concerning alternative IREDs (InfraRed Emitting Diodes) to
    be used with the Optotrak system.

    Do you have any experience with the Optotrak 3020 system and any other
    IREDs than the ones supplied by Northern Digital, I'd like to hear from
    your experiences and specifications of the alternatives used, including
    program settings (in the Optotrak Collect program, like strober voltage,
    pulse width etc), durability and availability (esp. in small quantities,
    I'm not gonna buy 1000 pcs :-)).

    On sufficient response I'll mail a summary to this listing.

    With best regards
