Focusing

monitor for focusing, select
present, will open and successive images will be sent to the monitor as quickly as
they are acquired. Because the time to acquire and read out an image varies directly
with the size of the CCD, the observed frame rate will vary greatly depending on the
CCD installed. With a short exposure time, it is not uncommon for the frame readout
time to be significantly longer than the exposure time.
will light and there will be a locked indication at the computer monitor,
indicating that temperature lock has been established. Note that some
overshoot may occur. This could cause temperature lock to be briefly lost
and then quickly re-established. If you are reading the actual temperature
reported by the application software, there may be a small difference
between the set and reported temperature when lock is established. This is
normal and does not indicate a system malfunction. Once lock is established,
the temperature will be stable to within ±0.05°C.
Note: If you are using the USB 2.0 interface, the Detector Temperature
dialog box will not display temperature information while you are acquiring
data.
