5. DESCRIPTION AND TECHNICAL SPECIFICATIONS
SWIR CMOS sensor
SNAKE-SW TECLESS introduction
Designed and fabricated by SOFRADIR, the SNAKE-SW TECLESS sensor is dedicated for flux imaging
applications in the SWIR band. On the one hand, it is responding to night vision, airborne tracking, surveillance
needs, and on the other hand, on various medical applications in preclinical and clinical such as real-time
intra/per/postoperative, oncology, dentistry and neurosciences, for example.
SNAKE-SW TECLESS includes a focal plane array (FPA) composed of a (640 x 512) pixels pitch of 15 µm each.
It is made of photovoltaic (PV) Indium Gallium Arsenide (InGaAs) on Indium Phosphide (InP) substrate
connected by bump bonding to a silicon readout integrated circuit (ROIC).
Standard InGaAs used in SNAKE-SW TECLESS allows to detect wavelength ranges between 0.9 and 1.7 µm.
The digital and analog functions are controlled by a serial interface. The readout of SNAKE-SW TECLESS
allows to read windows in cropping mode.
Spectral response
Typical curve (20°C) is represented on Fig. 3 :
InGaAs quantum efficiency between 900 and 1800 nm.

Description and minimum specification accessories
Power input
C-RED 3 requires a single power input, supplied in the package.
Power supply must provide a stable 12 V DC, with at least 1.5 A of current available (18 W) to properly power
C-RED 3.
The mating connector is a FISCHER CONNECTORS®S 102 A053-130+.
On the left, C-RED 3 USB back view. The yellow box shows the female power connector cabling.
On the center, C-RED 3 CL back view. The yellow box shows the female power connector cabling.
On the right, the female power connector. 1 and 2 represent the GND power connectors. 3 and 4 represent the +12VDC power connectors.
Always use the provided power supply.
Thermal management
The design of C-RED 3 camera is optimized to dissipate heat by the bottom face.
First Light recommend to fastening the camera with thermal grease between the support and the
bottom face of the camera.
Cooling system
The camera doesn’t have its own thermal regulation system to maintain a setpoint.
To maintain the detector temperature, C-RED 3 can use an external liquid cooling system sold separately.
For more information please contact First Light Imaging at [e-mail]
Communication interface
Control and data acquisition are done either through Camera Link®or USB 3.0 connection depending on the
model of your camera.

Since Windows® 7 does not support USB 3.0 natively, USB 3.0 support is heterogeneous, and performance is
hardly predictable. Please note that First Light Imaging will not provide any support for issues regarding the
use of Windows® 7.
Also, before using USB3 connection, the C-RED 3 USB3 drivers must be installed on the PC.
The drivers are included in the USB SDK library. By default, this library is installed with the GUI demo
software. Please simply install the demo software and the drivers will be installed.
Note:In order to have the full USB3 bandwidth, it is necessary with some PC to disable all the energy saving
settings (cf. C-RED 2-3 AN2 disable power saving for USB3).
Demo GUI software
The Graphical User Interface (GUI) demo software is provided in the USB key supplied with the C-RED 3
camera, or available on demand at [e-mail].
It is a dedicated interface developed by First Light Imaging which allows to control almost all the parameters
of the camera. This demo software has its own manual.
Powering up/down
Power ON:
When the power FISCHER CONNECTORS is connected to the camera, and the power supply to the line plug, the
camera is ON.
Power OFF:
Please use the CLI command “shutdown” from a simple terminal before turning off the camera. First unplug
the power supply from the line plug, then unplug the FISCHER CONNECTORS cable from the camera.
The shutdown command is recommended (especially to store the latest logs), however, the direct switch off
of the camera doesn’t damage it.
