1. INTRODUCTION
1.1 Scope
This manual covers the Owl Mini digital camera and all applicable components. Raptor recommends
that this manual be used to optimize camera operation.
1.2 Camera Care
Raptor cameras require no regular maintenance except occasional external cleaning of the sensor
window (the glass window between the camera sensor and the microscope or lens). Should any other
issues occur please contact your local agent.
To clean the sensor window: gently wipe the face of the sensor window with a small amount of optical
grade isopropyl alcohol and lens paper. Apply forced air again to remove any loose particles.
CAUTION —The camera’s sensor, and circuits are sensitive to static discharge. Ensure you are using a
static strap or are completely grounded at all times to release any static energy before you clean the
window.
CAUTION —Do not use acetone.

3.5 Connecting your camera to a computer
If using a laptop insert the Express Card to Camera Link adapter while the PC is switched off
and make sure it is secure. If using a PC, insert the EPIX controller card into the correct slot of
your PC. You can visit http://www.epixinc.com for further support issues.
Insert EPIX software key dongle into a USB port (the red light on the dongle should light up).
Boot up the computer.
Use the Camera Link cable to connect the camera to the computer.
Connect the other end of the Camera Link cable to the camera.
Carefully thread the C-mount lens onto the camera’s lens ring, rotating the lens in a clockwise
direction until it is securely fastened. Use the lens controls to adjust focus. We suggest that
the camera be mounted on a tri-pod or an optical bench.
Connect the 12V power supply to the camera.
The Owl 640 camera is compatible with all types of Camera Link frame grabber. However, our cameras
are extensively tested using Epix Inc. equipment’s XCAP, for this reason we recommend XCAP software.

Changing the settings on XCAP
You have the ability to change several settings to control the camera through the tabs in the control
window of the EPIX software.
4.4 Exposure
Click on the Gain Tab.
There is an option for Auto Level Control (ALC). When Auto Level Control is unchecked, you can
manually adjust the exposure and digital gain using the sliders or entering a specific value in the field.
It is recommended to start with auto gain on to get an image, then turning it off to fine-tune your image.
Figure 7: Gain Tab

4.5 Trigger
Use this tab to select the Readout Mode, and a Fixed Frame Rate value.
Figure 8: Trigger Tab
4.6 Auto
On this Tab, you can select the parameters for the Automatic Level Control, Including the speed, and
spread of signal taken into account. In this mode, the FPGA of the camera will automatically adapt the
exposure time and digital gain within the given frame rate to optimise the image quality.

4.7 Auto ROI
Use this tab to set the Region of Interest (ROI) used for the Auto Level Control; ROI gain will set an
overlay onto the image so you can track its position. By default, this will be set to account for the whole
image. Edit the values of Offset, Width and Height to place the Auto Level Control ROI over the image.
Figure 10: Auto ROI Tab
Figure 11: Active ROI Dark Area
In Figure 11, the ROI is contained within the small white box, and as such when centred on the black
case we can see the minor scratches but the sun light on the carpet has saturated the image.

Figure 12: Active ROI
However, when we move the ROI box to the carpet, Figure 12, where the sun is shining the camera
adjusts the exposure but the box becomes too dark to see any detail. This is an extreme example used
to illustrate this feature.
4.8 NUC
On this tab, you can select the parameters for the on-board Non Uniformity Correction (NUC); select
the 3point NUC Offset, Gain & Dark shown in Figure 13. Figure 14 and Figure 15 show the effect of
the NUC off and on.
