Acquiring Data
1. If you are using WinView/32 and the computer monitor for focusing, select
Focus
from the
Acquisition
menu. Successive images will be sent to the
monitor as quickly as they are acquired.
2. Adjust the lens aperture, intensity scaling, and focus for the best image as
viewed on the computer monitor. Some imaging tips follow:
•
Begin with the lens blocked off and then set the lens at the smallest
possible aperture (largest f-stop number).
•
Make sure there is a suitable target in front of the lens. An object with
text or graphics works best.
•
Adjust the intensity scaling (by clicking the
5%-95%
button at the
bottom left corner of the data window) and adjust the lens aperture until
a suitable setting is found. Once you’ve determined that the image is
present, select a lower setting for better contrast. Check the brightest
regions of the image to determine if the A/D converter is at full-scale.
