How to Adjust the Pinhole and
Collimator
Adjustment of pinholes can be performed
manually or automatically.
Temporary optimization of the adjustment:
The position of the pinhole relative to the detector
in terms of X-Y-Z coordinates contributes
substantially to image optimization.
Requirements to make the influence of pinhole
position changes on image brightness immediately
visible:
−
The image must be scanned by the
continuous scan method.
−
Select a fast scanning speed.
−
Measurement with Average Number 1 only
(no averaging of several measurements).
−
On the
Channels
tool in the LSM
Acquisition Parameter
tool group select
the pinhole diameter so as to have the best
possible image contrast (see Fig. 556).
•
Open the
Adjust Pinhole and Collimator
tool
in the
Maintain
tool group in the
Maintain
panel.
•
Select the pinhole to be adjusted from the
Name
list box.
•
Use the
Diameter
slider to set the smallest possible size which produces a good, high-contrast image.
This setting changes the pinhole diameter.
Image optimization can be effected with the
Range Indicator
or in the
Line-Scan
mode.
