Securing the EyeLink 1000 Fiber Optic Camera Head
The Fiber Optic Camera Head first attaches to a bracket that has several guide holes oriented
at a right angle to the camera (rightmost image of Figure 7-3). The holes interface with guide
pins on the Camera Head Clip (pictured at the left of Figure 7-2). The guide pins on the Camera
Head Clip slide into guide holes on the Camera Head Bracket to determine the camera
orientation. When the pins are in the center pair of holes the camera will be horizontally
oriented and parallel with the Mounting Bar (the Camera Level position). When the holes are
aligned diagonally with the guide pins, the camera will be oriented as required for binocular
recording (the Camera Angled position).

The top part of Figure 7-4 shows the Camera Head Bracket attached to the Mounting Bar
without the camera, in the horizontal or Level position for monocular recording (left) and
Angled for binocular recording (right). The bottom of Figure 7-4 shows the Camera Head
attached to the bracket and the bracket attached to the Camera Head Clip on the Mounting
Bar.
With the lens cap on to avoid dirtying the lens, screw a 35, 50 or 75 mm camera lens into the
threads on the Camera Head. See Table 2 of the current manual for recommendations on
which lens to use for the eye-to-camera distance that you desire. In general, the larger the lens,
the greater the magnification, and the longer the eye-to-camera distance that can be used.
Attach the Camera Head so the fiber optic cable is emerging toward the
center of the Mounting Bar. The Camera’s image orientation can easily
be changed in the Host PC application.
To mount the Camera Head, first attach the Camera Head to the Camera Head Bracket as in
Figure 7-3 (right) using supplied brass thumbscrews. Next align the holes on the bracket with
the pins on the Mounting Bar’s Camera Clip in either the Level or Angled position. Ideally, the
