1. INTRODUCTION
1.1 Scope
This manual covers the Owl 1280 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.
1.3 CameraLink Cable
If using a CameraLink cable not supplied direct from Raptor, for CE compliance we recommend using
a screened CameraLink cable with ferrite (100 ohms at 100MHz) fitted as close to the camera as
possible.

2. SPECIFICATION
2.1 Camera Specification
The OWL 640T digital camera is designed for applications requiring visible to SWIR imaging (600-
1700nm). The OWL 640T camera uses an InGaAS sensor with a resolution of 640 x 512 in a 12-bit digital
output. High-speed low-noise electronics provide linear response and sensitivity for rapid image
capture.
The Camera Link digital interface provides the most stable platform for data transfer and the camera
will work on any Camera Link standard card.
A Software Development Kit (SDK) is available for interfacing with custom software.

3. GETTING STARTED
3.1 System Overview
3.2 Mounting to Microscope
The OWL 640T has a standard C-Mount that should easily screw onto any microscope port.
3.3 Mounting to a tripod or optical table
The camera has a ¼-20 BSW (Whitworth), threaded hole to mount to a tripod or an optical table. The
image below shows an optical table mount with the ¼-20 BSW thread.

3.4 3rd PARTY SOFTWARE
Raptor supports a range of 3
rd
party software packages as per the matrix below.
In this guide, there is a quick overview of XCAP (http://www.epixinc.com/support/files.php) and Micro-
Manager (https://micro-manager.org). Should you have other software support specific needs, please
do not hesitate to contact our sales team on [email protected].
3.5 Connecting your camera to a computer
 Boot up the computer.
 Insert EPIX software key dongle into a USB port of your PC (the red light on the dongle should
light up).
 Use the Camera Link cable to connect the camera to the computer. Be sure to use the Camera
Link port closest to the trigger and power connectors on the camera. The 2
nd
port is not in use.
 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 640T 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.
If using a CameraLink cable not supplied direct from Raptor, for CE compliance we recommend using
a screened CameraLink cable with ferrite (100 ohms at 100MHz) fitted as close to the camera as
possible.

6. The camera controls are pre-configured in EPIX.
7. The control window on the right should reflect your chosen camera. For example, for the Owl 640T,
it should read - EPIX PIXCI EL8: Raptor Photonics OWL 640T. If not, you need to select a different
camera.
8. Check that the camera is communicating, see animated icon (Figure 4) on bottom right of control
screen.
