Appendix B:
EM Gain Calibration Code
Sample
CAUTION!
!
The information provided within this appendix is NOT
applicable to emICCD cameras.
The
EMGainCalibration.exe
file is sample code included with PICam which, when
built, allows PICam users to perform an EM Gain Calibration that may occasionally be
required by ProEM or Evolve systems.
NOTE:
Users with access to LightField do not need to build the
sample code in order to perform an EM Gain Calibration.
LightField includes
EMGainCalibration.exe
as part of its
normal installation. The fully-functional executable file is
located within the standard LightField installation directory
(i.e., where
PrincetonInstruments.LightField.exe
is
stored.
EMGainCalibration.exe
is an excellent alternative for developers who do not need to
create a custom EM gain calibration application. Once the sample code has been built,
it can be included as part of the standard customer installation process and allows users
to perform EM calibration on an as needed basis.
CAUTION!
!
When calibrating a ProEM or Evolve camera with a manual
shutter (e.g., ProEM:1600,) the shutter MUST be closed
manually before launching the calibration program.
This is not necessary for a camera with an internal electro-
mechanical shutter because the program will automatically
close the shutter before beginning the calibration.
B.1
EM Gain Calibration Procedure
Perform the following procedure to perform an EM Gain calibration:
1. If a data acquisition program is running (e.g., custom PICam application, LightField,
etc.) close it.
2. Verify that the ProEM or Evolve camera that is to be calibrated is the only camera of
its kind connected to the host computer and that it is turned on.
3. If the camera has a manual shutter, verify that it is closed. If necessary, close it.
