Sensor cables are included with the fNIR Imaging System and can also be ordered separately.
Photo-detectors: Silicon photodiode with integrated trans-impedance preamp
Photo-emitters: 730 nm/850 nm dual wave-length LED
Material: silicone rubber over-molded
Sensor Use with Young Subjects
When using 5 or 6 opcode sensors on young subjects, LED electrical current to the Main and Reference optodes must be adjusted down to adequately cover the A/D range in the provided COBI software. Source detectors are set at 2.5 cm for pediatric subjects but may go to 2 cm for infant studies. Settings need to be reviewed for each participant since factors such as bone density, skin color, perspiration, etc. may play a role. Aim for the middle of the A/D range by adjusting LED Currents and Gain, trying to keep gain as close to 1 as possible.
Cleaning fNIR Imagers and Sensors
All generations and models: Use an alcohol-based antiseptic to gently wipe the surface of the fNIR Imager unit or sensor; never use peroxide-based antiseptics.
For older Imagers or the test sensor
