the infrared LEDs may be visible as there is some overlap with the visible spectrum. A 940 nm
Illuminator is also available that is for most purposes invisible to the subject (noticeable
perhaps in only fully dark-adapted states), even when in the darkened scanner environment.
The tradeoff between these two illuminators lies in the 890 nm light being more instense and
therefore more strongly illuminating at greater distances. Both illuminators however are
sufficient for the 60-150 cm range of the Long Range EyeLink 1000.
To secure the illuminator with the power cable leading from the left. Secure the Illuminator to
its Mounting Clip (right side of Figure 7-5) with one or two brass thumbscrews from
underneath as pictured in the left side of Figure 7-5. Note there are black thumbscrews holding
the illuminator cover on – these are not involved in mounting the illuminator but will be used
at a later step.

Affixing the Mounting Bar
The Mounting Bar attaches to a Mount Base (e.g., Desktop Base, Screen Mount,
specialized
MRI Mount, Tripod Adapter, etc.) using two brass bolts (Figure 7-6, right) that are beneath
small plastic covers. Simply pry the plastic covers free with fingernails to avoid scratching them
or the Mounting Bar, and use a flathead /slotted screwdriver to affix the Mounting Bar.
If you have plans to use the Tripod Adapter, it has a standard ¼ inch thread in the bottom
(Figure 7-6, left) for use with standard tripods.

Cabling for Long Range System
Fiber Optic Cabling
: If not already completed, connect the Camera Head’s fiber optic cable to
the supplied fiber optic extension cable. The other end of the fiber optic cable goes to the
Camera Base Box which should be affixed to the back, left side of your Host PC using Velcro.
Ensure that the 12V EyeLink 1000 power supply is connected to the power connector on the
Camera Base Box.
