D.3 XEVA XC-130
Camera Installation D.3.1
To use a XenICs USB XEVA XC-130 camera you need to install the BeamSquared software from the
Ophir-Spiricon CD and the Xeneth software from the XenICs CD in either order.
You must run the XenICs CD and follow the directions for installing Xeneth. You cannot successfully use the
XenICs camera in BeamSquared unless the camera driver and calibration pack NUC files are available for
BeamSquared. The XC-130 camera cannot be connected to both Xeneth and BeamSquared at the same time.
The correct version of Xeneth must be installed for proper operation.
1. Insert the Xenics CD into a CD Driver.
2. Open Windows Explorer and select the CD Driver.
3. Navigate to the folder 2_Software\Xeneth-SW_and_Manual\Xeneth_Advanced.
4. For 32-bit operating systems run Xeneth-Setup-Advanced.
5. For 64-bit operating systems run Xeneth-Setup-Advanced64.
6. Restart the computer. The camera cannot connect without a system restart.
The operating controls for XEVA model cameras are simplified to provide the best possible measurement
accuracy for BeamSquared.
The InGaAs imager in the Xeva camera requires image correction processing to provide a useful image output.
Xenics cameras, including Xeva, employ special NUC (non-uniformity correction) files that must be downloaded
to the camera. These correction files are supplied by the manufacturer and are unique to each camera. NUC
files provide gain, offset, and bad pixel correction for specific operating settings such as exposure, gain, black
level, imager temperature, etc. BeamSquared provides controls to employ the necessary NUC file.
There are two (2) types of NUC files: TrueNUC files and standard NUC files. Both can be used with Xeneth.
NUC files end with a file extension of .xca and are also referred to as “calibration packs” or “camera
correction” files. Xenics provides a CD with each camera that contains the factory generated NUC and
TrueNUC files as well as a utility called Xeneth. This utility allows the user to test the camera and make
additional NUC files if necessary.
NUC and TrueNUC files fall into 2 general classes: High Gain (HG) and Low Gain (LG). For laser beam analysis
the High Gain NUC files are most frequently employed. High Gain NUC files give exceptionally better response
linearity than Low Gain.
TrueNUC files can be used over a broad exposure range and maintain good pixel correction. Only the
TrueNUC_HG file is recommended for use with BeamGage.
Regular NUC files are specified for operation at or very near the preset exposure in effect when the NUC file
was created. Using them outside of their set value degrades the camera’s image correction performance.
