FluoroMax-3 v. 3.1 (6 Mar 2006) Automated Polarizers
10-10
Note:
If the motor rotates during alignment of automated polar-
izers, immediately stop the procedure. Secure the polarizers in
their collars, then re-initialize the polarizers. Otherwise, the
alignment may not occur at the calibration position of the polar-
izers.
Note:
Adjust the polarizers with the room lights off or the
instrument covered with a tarpaulin. Stray light can
have a deleterious effect on the photomultiplier tube, or
make optimization of the alignment more difficult.
When complete, the software routine displays the measured anisotropy for each
emission channel (
S or T ).
8
Approve or retry the measurement based on
satisfaction with the result.
9
To quit, hit the Cancel button at any time during
the procedure.
Alignment
1
Turn off power to the polarizers and 1976 Ac-
cessory Controller.
2
Loosen the screws holding the polarizers inside
their collars.
Do not loosen the set screw holding the collar in the mount. FL-1044 and FL-
1045 autopolarizers have three set screws: two on one side of the collar, and one
on the other side of the collar.
3
Set the tension on these set screws.
They should not slip, but should allow easy manual rotation.
4
Set the polarizer crystals’ position.
They should protrude from the mounts far enough (~1/4" or ~6 mm) to allow
rotation.
5
Start the polarizers and accessory controller.
Caution:
Never attempt to manually realign FL-1044 or
FL-1045 polarizers.
