4.2.2 Assembling the CCD Camera
Gel Doc  XR
a) Place the Camera on the bench so that the two tripod mount holes are facing you.
b) Using one of the two knurled screws and washers attach the Gel Doc
 bracket to the
Camera as shown in the picture below. Use the tripod mounting hole that is closest to the
top of the Camera. Do not tighten the screws yet.
c) The black adapter ring provided (3 millimeters thickness) has a soft and a hard side to it.
d) Position this adapter plate on top of the Universal Hood II such that the soft side of the
ring is facing up and the ring is concentric with the round opening on the universal hood.

e) Place the Camera over the Universal Hood II by inserting the lens into the adapter ring.
f) Make sure that the front of the lens is in direct contact with the black adapter ring.
g) Verify that the lens is centered in the opening on top of the enclosure. To do this you may
need to move the entire body of the Camera and the ring so that the lens is also in the
center of the adapter ring.
WARNING: Failing to center the lens in the adapter ring and the hood can cause the
focusing ring located on the front side of the lens to mechanically rub or bind.
h) Secure the Gel Doc
 XR bracket (attached to the Camera) to the bracket of the Universal
Hood II using the screw and knurled knob (see pictures below)
i) Tighten the two screws of the Gel Doc  XR Camera bracket. Check that the lens is well
positioned on the black adapter ring for a complete light seal.
j) A completely assembled Camera will look like the picture shown below.
