When mirror (
10
) has been adjusted for
rotation
to give an optimum
peak value, then the
tilt
adjustment of this mirror can be made to try
and optimise the light throughput value further. (See Fig 11.- diagram
shows a close up of the mirror parts with the ellipsoid mirrors arm
assembly (
4
) in the up/open
Sample Loading Position
for clarity.)
Fig 11. Final Output Mirror (10) for Rotation and Tilt Adjustment
Using the long 2mm Allen key supplied, insert it into the M4 x 10mm tilt
adjustment grub screw (
29
), accessed vertically from the top of the
Selector™ optical unit (
1
) to pass by the lifting carry handle (
18
). (The
ellipsoid mirrors arm assembly (
4
) will be in the down/closed
Sampling
Position
.) Rotate the Allen key clockwise or anticlockwise to turn the
grubscrew (
29
) to obtain an optimum value for the throughput signal.
Note:
In adjustment for the tilt angle of the final output mirror (
10
) take
care not to block the path of the infrared beam with your fingers
when turning the Allen key.
